I can confirm this for openSUSE packages 4.4.81, happens to me every time. Could this be possibly related to bug 239925? Ok, looked into the source: The tray settings use KCategorizedView and I checked another application which also uses KCategorizedView (Amarok script manager) which also freezes. This seems to be a dupe of bug 239925. Updated to latest Qt 4.7 alpha build and the problem seems fixed now. So this may be related to Qt 4.6.x *** Bug 240455 has been marked as a duplicate of this bug. *** Thread 1 (Thread 0x7fbb46783760 (LWP 4849)):

I can prevent the crash by unlocking the widgets first. Can you confirm? with widgets locked, i can reproduce it. and yes, the backtrace i get is in Qt via KCategorizedItemView ... ugh. I am not at this particular machine right now, but the *freeze* appears no matter if widgets are locked or not. |
