thumbnail generation not working

[Colin Brace <cwb lim nl>]

Hello,

For some reason, thumbnail generation of video and text files is no 
longer working on my system (Gnome 2.10 under FC4). Gnome displays the 
generic icons for .avi, .txt etc. Thumbnails generated under FC3 are 
however still displayed. I have the standard video decoders installed 
(gstream, xine, mplayer). Video file size preferences is thumbnails for 
files up to 1G.

Suggestions anyone?
