The segfault is not from app, but from Python.

I wouldn't say that the traceback comes from python.
It obviously comes from (Py)GTK.

Not setting buffer to None fixes the problem:
{{{
def on_comment_focus_cb(self, widget, event):
if not self.comment_changed:
buff = gtk.TextBuffer()
buff.set_text("")
widget.set_buffer(buff)
self.comment_changed = True
}}}

Added '20090701T08:11:06' by 'mnowak'

This is fixed for some time and is not crashing anymore.

Current code:

{{{
def on_comment_focus_cb(self, widget, event):
if not self.comment_changed:
widget.set_buffer(gtk.TextBuffer())
self.comment_changed = True
}}}

Have a look at v0.0.4 or git/master.

Yes, and still - it's not the abrt's fault, even if I'm doing smth wrong with the textbuffer it shouldn't segfault, but raise an exception.
