Bug 253611

Application: amarok (2.3.2)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-25-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I had just copied 3,4GB of music into my collection, amarok was turning grey during the copy process.
After the copy process finished, amarok came back to normal and I enterned the search term Kerri.
Amarok Segfaulted and crashed.

- Unusual behavior I noticed:
Amarok runing under gnome is exhibiting strange screen build up. Maybe for a seperate bug, but sometimes you have to minimize and maximize amarok in order to use the interface. The colors are also have grey of amarok and half gtk colors. Many times the interface hangs for several seconds before you can input text.

- Custom settings of the application:
Discgos Script is installed
Ultimate Lyrics Script installed
Brazillian Radio Station Script Installed
Automatic Moodbar Generator Installed (does not work)

Music collection is on a NAS (Synology DS 509+) on the network.
Moodbar is turned on.
Using the XINE engine
Using Amarok from the Ubuntu PPA

Any other questions feel free to ask.

The crash can be reproduced some of the time.

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