--- Comment #36 from Thomas Fischer <fischer unix-ag uni-kl de>  2011-09-16 07:09:54 ---
I just want to contribute my backtrace. I differs from the previous ones that
it contains source code filenames and lines like #26, but uses a more recent
FreeType version (2.4.6). My crash happend in Konqueror/KDE 4.6.5 using Qt
4.7.3 in Gentoo Linux.
