Comment 1 David Jarvie 2012-03-19 21:43:05 UTC 
If you start KAlarm again after it crashes,  without logging out, does it crash again sometimes?

If so, after it crashes, can you please open a terminal window, and then start KAlarm from there, by typing "kalarm" followed by ENTER in the terminal window. If it crashes again, please copy the output from the terminal window to this bug report.
Comment 2 David Jarvie 2012-03-26 12:31:41 UTC 
Information supplied by the reporter, by email, 19/3/2012:

KAlarm after the restart, manually, don't crashes again, it crashes, and not at all times, only after the first start, at login.
Comment 3 David Jarvie 2012-03-28 21:14:02 UTC 
Do you see any error message windows appearing briefly, before KAlarm crashes?

Comment 7 David Jarvie 2012-03-28 23:38:14 UTC 
I've committed a fix, which I hope will prevent the crash if the error I suspect is triggering the crash occurs. There is still a possibility that KAlarm could terminate cleanly instead of crashing - if you see the same problem after updating to a new version of KAlarm, please reopen the bug.

The fix will be in KDE 4.8.2. It will also be in KDE/kdepim 4.4.12, if that is ever released (which is unlikely).
