--- Comment #23 from Christoph Feck <christoph maxiom de>  2011-12-21 14:43:42 ---
Using VLC 1.1.12 on KDE 4.8rc1 with Qt 4.8.0, I can still reproduce the crash
with the steps provided in comment #10, so it either is still not fixed in Qt
4.8, or the fix did not affect KDE.

Is there a link to an open Qt bug?
