Hi,
At first as a standard procedure of course ;p, you may want to try to debug it, just enable debugging information when
compiling, sometime with "nicely" gdb tell you which part making that mess.

Subject: GtkItemFactory stuff troubles
Date: Sun, 24 Jan 2010 14:05:48 +0100
Hi,
I'm having troubles with GTkItemFactory stuff. So I've trimmed the buggy part of my app (about
5000 lines long) to something small. The problem is I get a segfault whenever I press <ctrl><R>
to open the RSS Feed window immediately followed by <esc> to close the window so I think there is
something wrong with the menu bar and accelerators but can't find out what.
Thanks in advance for any hints. Here is the code:
#define _GNU_SOURCE
#define _ISOC99_SOURCE
