Drapes 0.5.2-3.1 doesn't do anything on my Debian Squeeze machine
 

I recently downloaded the package Drapes and it seems to be very buggy. The first time I ran it, it seemed to work fine but it froze while I was viewing the preferences. Since then all it seems to do is take up all available possessor time but it does nothing. The is still the case after rebooting.
I started it in the root terminal and this was the output:
debian:/home/andrew# drapes

(/usr/lib/drapes/drapes.exe:5916): GnomeUI-WARNING **: While connecting to session manager:

Any helpful suggestions will be greatly appreciated. If I can't get this to run right I'm sure I'll just have to forget the whole thing, but I really would like a package that rotates my backgrounds for me.
Does anyone know if there might be other more stable packages that do that?
