Application: kalarm (2.4.10)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Sleeping :) I set an audio alarm and went to sleep. I was woked up by my second alarm (in phone) only to find that this one had failed because of the crash of application.

- Custom settings of the application:
I set custom song as an alarm. The song is localted on my external memory disc (Samsung S2). The device itself works good, there was also no problem in playing song when I clicked "Try" button before setting the alarm.

The crash can be reproduced some of the time.

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