Hi,
I can not lauch my amarok anymore.
Who can help me?

More information:

I am using mandriva 2009.1 x86_64.
$ amarok --version
Qt: 4.5.2
KDE: 4.2.4 (KDE 4.2.4)
Amarok: 2.1.1

When I try to launch amarok I got the follow error:
$ amarok
<unknown program name>(18517)/: Communication problem with "amarok" , it probably crashed.
Error message was: "org.freedesktop.DBus.Error.NoReply" : " "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken." "

To get the full strace here is the link:

I strongly suggest you update to Amarok 2.2.1 first, version 2.1.1 is completely outdated.
Also, that strace doesn't really show something useful, try starting Amarok from a konsole using the options '-d --nofork' (without the ') and check if there is a better output.
