Abrt filed this I think: https://bugzilla.redhat.com/show_bug.cgi?id=1158398

Thanks for a bug report. Better to paste backtraces inline, to be able to search for duplicates easily. If you have a message which reproduces the crash reliably, then it'll definitely help to investigate the issue. Just disable preview (Ctrl+M) in the offending folder, selected the message, right-click it and choose Save as mbox. Remove any private information in it, like by editing the text and censoring it with 'x'. The crash happened in the webkit code, what is your current webkitgtk3 version, please?

Sorry about the stack trace Milan - they're generally quite long and I'm never sure if I should paste them or attach them :(

When I import the attached mbox message, it doesn't crash evo. If it doesn't help you debug, I can maybe send you the unedited mbox message privately if required, Milan. Or I can attach it to the rhbz and you can mark it as private.

Hmm, works for me without crash too. Preferably send the message as stored on the disk (~/.cache/evolution/mail/<account-uid>/... or ~/.local/share/evolution/mail/....) to my email, with the bug number/link in the subject, thus I don't overlook it. I will try whether the verbatim copy will cause the crash and then let you know. You can find the message by Mesasge-ID header, which the attached has:
   <D3B111151A167849A02B58E9BB1863D90197AAB4F887@UH-MAILSTOR.herts.ac.uk>

Sent. 

I couldn't get evolution to import the file to test, though. I right clicked on the file in nautilus and used "open with evolution", but nothing seemed to happen (even after adding an .mbox extension).

Oh, but when I try to see the mail I sent you, evolution crashes if I don't disable the preview mode - so that sort of confirms it. Hopefully evo will crash when you try to see the mail too :)

Thanks, the message is "missing" a "From email" line as its first line, it's a limitation of the import. I imported it and running webkitgtk3 2.2.5 shows the message correctly, but when I open it with webkigtk3 2.4.6 or 2.4.7, then it crashes. I run it under valgrind and it claims a use of some invalid pointer just before the crash, thus it looks like a bug in webkit on the first look. I'll investigate further (when 2.4.6 will be built on my main machine). It can be also something with connection to gtk. I'll know more later.

Hrm, locally built webkigtk3-2.4.7 with locally built atk-2.14.0, glib-2.42.0, glib-networking-2.42.0, gtk+-3.14.3 (some outdated git clone, right after 3.14.2 release) and pango-1.36.8 under Fedora 20 environment doesn't reproduce the crash. The other library versions are pretty much the same as I have in my Fedora 21 machine, where I can reproduce the crash. That makes me think that the issue is somewhere else, probably in another library used by webkit (I'm plain guessing here).

Tomas, could you look on this, please? It's crashing in the webkit code, maybe you noticed something similar earlier. If Ankur will be fine, I'll give you the reproducer message as sent by Ankur to me. Only note thatI tried to reproduce this under rawhide, with no luck. I could reproduce on Fedora 21 though.

(In reply to comment #8) If Ankur will be fine, I'll give you the
> reproducer message as sent by Ankur to me. 

Sure. The mail doesn't have any security critical information - it just has peoples names :)

reproducer email

This is a sanitized version of the email, which also reproduces the crash on Fedora 21. It seems to be related to the To filed, where are quite many people added.

I ran into the same crash (according to ABRT/libreport, see downstreams bug report) with a very different email. When opening a specific email message evolution reliably crashes. This can be reproduced. It happens to one of two exactly identical emails (diff is empty). The only difference is the filename and read/unread state. Opening the unread email works, opening the read email crashes Evolution. This email contains HTML content only, no ordinary text. Shall I send you the mail to your email address?

If you get the same backtrace then it's not needed, the reproducer is attached above. The problem is to figure out what's going wrong, while it looks like a webkit issue, not necessarily evolution's.

I got another email causing this crash. When trying to reproduce the bug I found this strange behavior:

1. When running evolution with mail component and email preview open, evolution crashes when opening the e-mail. This time it affects both a read and an unread email.
2. When disabling email preview in the mail component, evolution does not crash any more when selecting the email. Even double-clicking on the email does not crash evolution.

I doubt this is related to the "To" field (as in comment #10) since I only have one single recipient (~40 characters) without any special characters whatsoever (subset of us-ascii: latin letters plus <, >, @ and space).
This time again I did have two identical emails with different status (one was read, another one unread) before the bug happened.

I have not seen this crash in a few years. Also, with the original E-Mail I cannot reproduce it either. This bug report could be closed IMHO.

Thanks for the update. I'm closing this.
