Description baruch60610 2011-02-21 05:14:35 UTC 
Application: amarok (2.3.2)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic-pae i686
Distribution: Ubuntu 10.10

-- Information about the crash:
When I have a selection of music I want to make into a playlist, if I "replace" a non-existent playlist, Amarok crashes.  It appears that if I simply "append", the program doesn't crash.

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault

Comment 1 Myriam Schweingruber 2011-02-21 08:18:23 UTC 
Do you have a Media Device attached? The crash appears to be triggered from the Media Devices stack, see also bug 243393
Comment 2 baruch60610 2011-02-21 08:41:56 UTC 
I don't recall whether I had a music player attached.  As of right now, I cannot reproduce the crash even with a music device attached.  I don't recall what programs I had running before.

This bug may not exist, or may be related to some other program.
Comment 3 Myriam Schweingruber 2011-02-21 12:13:59 UTC 
Thank you for your fast feedback. I close this report for now as working for you, please feel free to reopen it if you can reproduce this crash.
