Bug 310439

Application: amarok (2.6.0)
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.5.0-19-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:since upgrade 4.9.3 amarok behaves as it was sometime ago, which is a bug. When trying to change an internet radio station or when listening to MP3 and then trying to switch to a radio station it simply don't. I must restart amarok in order to listen to a station. This is very annoying again. The crash occured a couple of times when I was restarting amarok to listen to a station

The crash can be reproduced some of the time.

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