are you using any 3rd party effects?
Yes, - Zoom Desktop by kbroulik - Maximize by mgraesslin I have uninstalled and restart in a moment
*** This bug has been marked as a duplicate of bug 318269 ***
@Eric - did only removing those effects resolve the situation? - can you re-enable them w/o causing the crash? - does the normal "login" effect work (w/o crashing)?
I think Martin is right I'm using bespin window decoration I can't test before the next week (holidays).
We'd then have introduced an ABI break in the deco plugin. 68 virtual void showApplicationMenu(const QPoint&) = 0; 69 virtual bool menuAvailable() const = 0; at least broke ABI in kdecorationbridge.h - but that should only affect compiz, not deco plugins.... Eric, recomppiling bespin would be sufficient to solve the problem then, but also please attach ~/.kde/share/config/kwinrc (hoping that there's some real third party effect and we just forgot to bump the effect API version - not really broke the deco ABI)
