Description Hagai Kariti 2011-03-19 22:14:59 UTC

Application: amarok (2.4.0.90)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
What I was doing when the application crashed:
- Activated the Amparok script, got a syntax error
- Deactivated it
- Opened the Manage scripts window, found amparok, clicked "details"
- Closed the window via the X button
- Tried Manage Scripts again
- Bam!

The crash can be reproduced some of the time.

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

amarok (2.4.1) on KDE Platform 4.6.3 (4.6.3) "release 4" using Qt 4.7.3

- What I was doing when the application crashed:

I've installed some scripts using "Managed Scripts", and Amarok crashed when I pressed ctrl+q to quit amarok.

New crash information added by DrKonqi

amarok (2.4.1) on KDE Platform 4.6.3 (4.6.3) using Qt 4.7.3

- What I was doing when the application crashed:

- Open the Manage Window
- Close it
- Open it
- While it was opening (not yet showing) I clicked the button again. But I guess it was already failing then.

I guess in my version it wasn't fixed yet but looking forward to updating. Thanks :D

Comment 7 Kevin Funk 2011-07-05 09:51:55 UTC

@Benjamin: Please test with the upcoming 2.4.2 rc. Should be fixed.
