Hi,

Trinity didn't install cleanly on my system , never worked correctly  , 
and now I need to clean things up. we have highly customized systems 
using local package repos, the install failed and I forced the trinity 
install using dpkg on the advise of someone who "knew", so this should 
not be taken as a comment on trinity quality.

My latest problem is that the uninstall is also failing, preventing me 
from switching back to kde4.

Any advise on getting past this would be greatly appreciated.
