Bug 240845

Version:           2.3.0 (using KDE 4.4.2) 
OS:                Linux

Amarok ceases to be able to play any sound after trying to connect to a radio stream that seems not to be working. Trying to close amarok results in a crash. 


From the bug assistant:
This bug may be a duplicate of or related to bug 196320.

Possible duplicates by query: bug 237934, bug 227790, bug 225839, bug 221431.

Reproducible: Always

Steps to Reproduce:
Select from the "Internet" playlist a radio stream that does not work. Play.

Actual Results:  
Amarok tries to open the stream and fails. From this moment on, it won't play anything else and will crash after a while.

Expected Results:  
It should have played the stream.

Initially tried to report this with the assistant, but would not submit the bug due to an "unknown error". Here is the report it would have sent:


Application: amarok (2.3.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Amarok crashes when opening a radio stream that (seems) doesn't work. 

The crash can be reproduced some of the time.

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