[Pkg-kde-extras] Bug#612895: gtk2-engines-qtcurve: Evolution segfaults when using qtcurve style for GTK-apps in KDE

Fri Feb 11 11:50:35 UTC 2011

Package: gtk2-engines-qtcurve
Version: 1.8.5-1
Severity: important

When starting evolution using the qtcurve  GTK style (from system-settings ->
Appearance -> "GTK Styles and Fonts") it keeps segfault'ing

Below is a backtrace from gdb showing that libqtcurve seems to be the culprit:

I've managed to work around the problem by commenting out the line

"export GTK2_RC_FILES=/<myhomedir>/.gtkrc-2.0-kde"

from the file .kde/env/gtk-qt-engine.rc.sh, but that file get overwritten by
something from time to time - which is quite annoying.

I've attached .gtkrc-2.0-kde for reference.
