[maemo-developers] Possible bug in /usr/lib/libglib-2.0.so.0

[From: Detlef Schmicker]

Hello,

I have a strange problem: maetronome.garage.maemo.org

(A port of GTick) crashes with bus error. I tracked down the problem
with gdb and strace and the problem is connected to the file 

/usr/share/themes/default/gtk-2.0/gtkrc.cache

If I delete it, the crash does not happen and everything works fine. I
attach my output from gdb and strace. In case somebody wants to
reproduce, think of LD_PRELOAD !!

I seems that glib crashes during processing of gtkrc.cache

Any tips? Any workarounds?

Thanks a lot

Detlef
