Installation of this package breaks my kde4 ...
- After installing it, plasma seems to become crasy, no more text on items, and while trying to launch back kde4, it can't start ...
- While trying to launch amarok i've got a message saying that there is no multimedia backend ...
I can't use it :/

For those who get the same problem ( if there is ) uninstalling amarok-nightly and dependency from command line resolve the plasma problem :
sudo apt-get remove amarok-nightly && sudo apt-get autoremove

-------------------------------------------------------------------------

End of konsole output while trying to launch amarok ( if need more, tell me ) :

Amarok has crashed! We are terribly sorry about this :(

But, all is not lost! Perhaps an upgrade is already available which fixes the problem. Please check your distribution's software repository.
