Bug Fixes in Multimedia
Fixed possible GUI freeze when Amarok was showing the dialog for installing mp3 support. Patch by Sascha Sommer:
"The problem seems to be that EngineController::canDecode runs in a seperate thread than the gui thread. Opening up a Kmessagebox there will prevent amarok from handling all gui events and everything will freeze. I therefore put the dialog into an extra function that will later get called from the statusBar."
