Bug 326396

Application: kalarm (2.10.6-ak)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
Adding an existing KAlarm calendar to Kontact. Both KAlarm and Kontact were running at the time.
Imported .cal file was given the display name of "KAlarm Active Alarms", defaults were accepted and .cal was therefore r/w. 
Upon pressing the 'OK' button, KAlarm crashed, but Kontact did not seem to have been affected.
Restarted KAlarm and the same .cal file now shows in KAlarm as both "KAlarm Active Alarms" and the default "Active Alarms".

Expected behavior would be that Kontact shows the calendar as "KAlarm Active Alarms" whilst KAlarm would show it as "Active Alarms".
Alternatively, if the alarm names are shared between applications, the existing calendar name should be automatically filled in, the moment it is added to another application, or -when a name already exists- the new name should be rejected with a notification, and replaced with the existing name.

-- Backtrace:
Application: KAlarm (kalarm), signal: Segmentation fault
