KDE 4.6 RC2 from opensuse. Open local samba share via smb:// in konqueror or dolphin, find some video file (sintel_trailer-720p.ogv), open with: 1. Dragon player: see black screen 2. Kaffeine: See error message "Cannot find input plugin for MRL "smb://192.168.1.150/common/films/trailer/sintel_trailer-720p.ogv". 3. vlc: the only player that did work (interesting, that this one is non-kde app), but before it started playback, notification area showed file copy progress to "/var/tmp/kdecache/..." - too bad for big files.
