Description andysem 2013-11-18 12:29:27 UTC

I'm on Kubuntu 13.10, x86_64.

When I try to start a directory comparison, I press the Directory comparison button on the main scree, and then try to select one of the directories to compare by choosing Other in one of the combo-boxes below. Then Meld crashes with the following backtrace:

Program received signal SIGSEGV, Segmentation fault.

The problem doesn't happen if I try individual file comparison instead (the combo-box opens the standard file selection dialogue).

Comment 1 andysem 2013-11-18 12:31:36 UTC

Forgot to mention that Meld version is 1.8.1.

Comment 2 Kai Willadsen 2013-11-18 19:51:27 UTC

Does this happen every time?

If you run Meld from a terminal, do you get a Python traceback? Unfortunately the stack trace doesn't really help much.

Comment 3 andysem 2013-11-18 21:24:37 UTC

Yes, it happens every time.

The console output is as follows:

Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 14: reading configurations from ~/.fonts.conf is deprecated.
/usr/bin/meld:167: GtkWarning: gtk_tree_model_filter_get_value: assertion 'GTK_TREE_MODEL_FILTER (model)->priv->stamp == iter->stamp' failed

Comment 4 Kai Willadsen 2013-12-13 23:09:55 UTC

Sorry for the delay. I'm pretty sure that what you're seeing is a bug in GTK or the oxygen theme, take your pick. Either way, the crash isn't anywhere in Meld, so I'm going to close this.

This bug sounds like the problem you're seeing:
https://bugs.kde.org/show_bug.cgi?id=326424

Thanks anyway for the bug report.
