gdb backtrace of the segfault

I am using evolution 2.30.3 in a fresh install of Debian Squeeze on AMD64 (but with data kept from older versions). Since this fresh install (aprox. a week ago) I am seeing very frequent segfaults with evolution. These segfaults are happening when I am wiewing mails.

Step to reproduce :
1-launch evolution
2-read some new or old mails
3-after "some" (5 or 10) mails, evolution will crash with a segfault just after a mail is selected.

The segfault always occurs at the same place (a backtrace is attached).

I suppose that this bug is not easily reproducible, because it renders evolution nearly unusable for me so it could not have gone unnoticed (and I did not find anything similar in the bug tracker).

I will attach other information and a "workaround" in following messages.

debug output of evolution

This is a debug output of evolution (obtained with CAMEL_DEBUG=all) corresponding to the same execution which gave the attached backtrace. I only give the end of the file.

workaround for the segfault

This "patch" is a workaround to this crash. The segfault is raised when some incorrect GError data are freed (when a new error should be created). The faulty GError comes from a DBUS message. By changing the try_open_e_book function so that it is a really synchronous function (i.e. it calls the e_book_open function) the segfault have disappeared.

(I am using the setting to only load image in HTML mail if the author of the mail is in y contact list, if that may explain why the contact list is accessed when I am viewing mail.)

I understand that this is not a correct patch, even though I did not notice any serious drawback with applying this patch.

As I know too few of Gnome and absolutely nothing of DBUS I did not find from where is sent the faulty message (containing the erroneous GError data), so I don't know if the problem really is in evolution or in DBUS (but I have no random crash except in evolution).

However if there is some other things that I can look at to help debug this issue, please tell me what.

https://bugzilla.gnome.org/show_bug.cgi?id=557613#c104 has similar traces.
Comment 5 Milan Crha 2011-02-16 16:31:58 UTC
Hrm, I thought this was fixed by some of Chen changes, but looking into the logs where I would expect such change I didn't find any after 2.30.3 release. Let's have this opened and search for a reproducer, the best with some latest code, than with 2.32.2-, as there is not planned any update, and the code might change anyway, even I didn't find the change (I could search incorrectly).
Comment 6 Milan Crha 2011-09-02 06:28:28 UTC

Comment 7 Akhil Laddha 2011-10-20 10:13:28 UTC
Can you please check again whether this issue still happens in Evolution 3.0.3 or 3.2.0 and update this report by adding a comment and changing the "Version"
field? Thanks a lot.
