Fixed bug which caused Phonon backend error messages to be suppressed

When the mediaplayer receives a state change into the ErrorState, it
calls pause() on the media object.  Previously, this caused the
backend to transition into PausedState.  When the mediaplayer subsequently
called errorString() to retrieve the error message, an empty string was
returned because the backend was no longer in the ErrorState.
