Package: libqtgui4
Version: 4:4.5.2-2
Severity: normal
On my system (debian testing) with kde4.3, nvidia cards and driver and xinerama enabled libqtgui.so.4.5.2 gives a segfault in creating the color palette on kdm startup (kdmgreet).
Disabling xinerama solves the problem. The problem was not present before upgrading, but i don't know which versions were installed (kde 4.2.4 i think).
