[KPhotoAlbum] patch: crash, if no video kpart found

[Henner Zeller]

Hi,
If there are no KParts found to display videos, KPA crashes, because
_playerPart is never initialized. Reason: etype is initialized with
NoError .. which it still is after the loop through zero parts.
In addition to that, the actual error was never displayed but always NoWidget.

cheers,
