KAlarm window freezes

[Benjamin Tegge]

The KAlarm freezes randomly. Freezes can be reproduced when modifying an existing alarm configured with an audio alarm, which will open a new window, and clicking the try button to test the alarm, which will again open a new window.

Launching kalarm from terminal returns the following output:
$ kalarm
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.

Note: KAlarm is also not recognized by unity launcher.

Rebooted my system, Kalarm is now recognised by unity launcher. The application itself does not seem to freeze (now, set alarms were not executed before the reboot) but the application window seems to be rendered wrong in unity, like it froze. Doing a combination of minimising, maximising and moving the window to other workplaces brings the window "back to live".

I'm using the nvidia-current-updates graphic driver.

The issue still persists on new hardware, with Intel graphics and no proprietary display drivers involved.
