EDIT:
QtCurve, Adwaita and several other styles are also resulting in a crash; the only style that I can confirm is working is "Redmond" style for GTK2 apps
The only important thing seems to be the style selection for GTK2 apps, the style of KDE itself doesn't matter (as far as i tested it)

EDIT2:
As expected under a simple windowmanager, i tried IceWM, no problems.
