Hello,
I've encountered a new bug that was introduced by SVN commit: 204414.
Program: gimp
commit 88ecd59c3436d302b644a5d25c1938c0e7b60ae0
Author: Michael Natterer <mi...@gimp.org>
Date: Tue Feb 5 20:43:53 2013 +0100
GCC: 204414
uname -a:
Linux marxinbox 3.7.4-gentoo #6 SMP Mon Sep 30 20:53:52 CEST 2013 x86_64 AMD
