Sigh.

Look, either way I'm carrying this patch in Fedora because it fixes
a bug that is actually being reported by users (and by abrtd as well).
If you both want to wait until 3.2 to actually submit it to Linus,
then OK.

Honestly, I'm just glad we actually run with the debug options enabled
(which seems to be a rare thing) so bugs like this are actually found.
Thanks for the fix.
