As I now found out this is no regression, i.e. I can also reproduce this using KDE SC 4.8.4 with a basically identical backtrace. The crash only happens if you have Konqueror on the secondary monitor. If it is on the primary one everything is fine. DxSadEagle said on IRC about this: > IIRC it was something about how our notion of a screen and Qt's notion of a screen didn't > match or such.
