All GTK+ builds newer than 2.10.9 crash on Win32

[MuldeR <mulder2 gmx de>]

Hi!

I'm not sure if this is the right place to post this bug report, but here we go: It turns out that all GTK+ builds after v2.10.9 crash on some Win32 machines - including mine. The application I am referring to is Avidemux (http://www.avidemux.org), an OpenSource cross-platform video editor and transcoder. The user interface of Avidemux is based on GTK+. There also is a QT4 version of Avidemux though. I'm very interested in the development of Avidemux for Win32, since I'm on WindowsXP. The application is working great so far. But at a certain point I encountered mysterious crashes: The application was disappearing suddenly without any notice. This was happening with features that normally work stable. Also we were not able to track down the reason for the crash - no useful information could be obtained from the Log or the Debugger. Furthermore only a few people encountered the problem, others were unable to reproduce them. So I began to check various dependencies, including t
he GTK+ libraries. Finally it turned out that it was GTK+ which caused those mysterious crashes! As soon as I downgraded to GTK+ v2.10.9 everything worked 100% fine again. All newer builds I tested (v2.10.11, v2.10.12 and v2.10.13) cause crashes! Are there any known problems like this? For information: My system is WindowsXP 32-Bit SP-2 running on an AMD AthlonXP 2800+.

Here is some information from the Windows Debugger:

This is what gdb said:
