Crashes with GTK 2.8.12 and above

[Enrico TrÃger <enrico troeger uvena de>]

Hi,

I have some problems with newer GTK versions(2.8.12 and above) and my
application(http://geany.uvena.de). It crashes with segmentation faults
inside GTK. With GTK 2.8.10, it works at its best.
I and some other people tested it with GTK 2.8.12, 2.8.13 and 2.8.16
and crashes randomly. This means, sometimes the application works a few
minutes, somtimes a few seconds and sometimes it crashes before(or
while) the main window is initialized. It seems, that no special action
is necessary, only click somewhere, on a scrollbar, on the file open
dialog or whatever.

I have no idea, for what reason it crashes, so if anyone knows this
issue or have any hints, I would be really grateful.

If you need more information, please ask.

The following are some backtraces from gdb on different systems, I hope
they are at least a bit helpful. The first and last call in my code is
in main.c in line 577, this line calls only gtk_main().

This one I get on FreeBSD with GTK 2.8.12:

The following two are from Debian testing with GTK 2.8.16:

This one is from another Debian testing system which installed debug
libraries of GTK
