Correct

Krusader is an old-skool twin pane manager a-la mc and most definitely doesn't 
use the same kpart, but also doesn't do pretty thumbnails.

No problems here either, which makes me suspect the thumbnail/preview plugin 
being used which I did have problems with in the past.  I _think_ that the 
default one shipped with dolphin is fairly basic and doesn't do video, so 
there are a number of plugins out there that do the video that his distro may 
have shipped with, like mplayerthumbs.  First try disabling video 
thumbs/previews, then try uninstalling whatever plugin is installed.  If that 
doesn't work raise a bug :-)

Oh, one other debugging technique, try logging in as a new user first and see 
if they have the same problems.  If not, then you know it's your config and 
not the app.
