Version:           svn r913322 (using Devel)
OS:                Linux
Installed from:    Compiled sources

I've compiled amarok from source (complete rebuild) using KDE4.2 snapshot packages for arch linux (http://pkg.eth-os.org/kde-svn/i686).

When starting amarok, it shows the following error on the console and then segfaults:

----------------------
KCrash: Application 'amarok' crashing...                                                                     
sock_file=/home/dv/.kde/socket-rincewind.frozenbrain.com/kdeinit4__0                                         
<unknown program name>(26429)/: Communication problem with  "amarok" , it probably crashed.                  
Error message was:  "org.freedesktop.DBus.Error.NoReply" : " "Message did not receive a reply (timeout by message bus)" "

The backtrace looks like this:
