Application: amarok (2.4.3)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:

I installed Hupnp 1.0.0 (not from ubuntu repositories), installed cagibi, and then kio-upnp-ms.
I launched Amarok, activated the Upnp module in Amarok...
Amarok found a upnp share : Twonky
The Upnp module was in "Counting..." Status.
I waited very long, maybe 2 or 3 hours, but the status was always "Counting...", and nothing was listed in the Twonky share.
Then I double clicked on the twonky share, and CRASH.

Anytime I double click on the share, Amarok  crashes. He can detect the share, but doesn't list anything in it.


- Custom settings of the application:

Upnp module activated

The crash can be reproduced every time.

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