[Geany-devel] Crash when using splitwindow plugin

[Wolfgang Ocker]

Sometimes my home built Geany crashes with a segfault when I use the
window split function.

Build info:

        Linux Fedora 10, updated,  uname -a:
        Linux goedel.recco.de 2.6.27.15-170.2.24.fc10.x86_64 #1 SMP Wed
        Feb 11 23:14:31 EST 2009 x86_64 x86_64 x86_64 GNU/Linux
        
        Geany svnversion: 3603

I built and installed geany with

        ./autogen.sh; make rpm; sudo rpm -Uvh ...

Gcc Option -O2 is used for compiling.

I start Geany, open a file and use "Tools->Split Window->Vertically" (or
Horizontally) and sometimes it crashes then. Below a stack trace of such
an event ...
