Cnfirmed on Fedora 13. Amarok crashes with ~70% reproductibility when I try to navigate trough "Places"
Using regular filesystem tree view works ok.
--------------------------
My packages:

qt-4.6.2-17.fc13.i686
kdebase-4.4.3-2.fc13.1.i686
amarok-2.3.0.90-1.fc12.i686

Please update your Amarok version to 2.3.1 and install the debugging symbols, your backtrace is not really useful.

Crash still occurs after update, backtrace with debug symbols insstalled
Amarok version installed:  amarok-2.3.1-1.fc13.i686

Finally found time to reproduce. Submitting now from Kubuntu 10.04 in a VM (Easiest way to install the Debugging Symbols).

To reproduce with a new User just add something to Places usind Dolphin and make sure it is visible in all Applications. After that the described behavior starts.
