Application: amarok (2.4.3)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I jousted several music files to my collection. They were all encoded in FLAC. Not seeing them appear, I requested an update to Amarok.
Still nothing. I decided to quit and relaunch the software.
I have a segmentation fault at startup, I see the main window gray and then it crashes.


- Custom settings of the application:

I have an opportunity for the crash: the names of the files added are not encoded in UTF-8 and I saw a few accents in the shape of question mark.
Yet first I added a folder containing accents such as non-UTF-8, I also restarted Amarok and Amarok had indeed found the tracks and read without problems ...
That's why I can not be sure that the problem is the encoding Iso and accents of the names of new files.

The crash can be reproduced every time.

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