xine cannot detect plugin for files if played directly from folderview


I am using KDE 4.1 in opensuse 11.1. I have my desktop folder in folder view mode on the plasma dashboard. There are some video files there. When I try to play those video files from dolphin, they
play fine; but when I play them from the folder view on the dashboard I get the following error message:

02:53:51 PM: xine: cannot find input plugin for MRL

Xine does not seem to recognise desktop:/ format. Please suggest.
