evolution won't start

[31HIMEL <31HIMEL@cua.edu>]

I was using evolution quite happily until a few weeks ago.  Then after an 
upgrade it will not start and gives the following error messages:


evolution-shell-WARNING **: Cannot access Bonobo/ConfigDatabase on wombat:

Can anyone please tell me what I should do to rectify the situation?  As far 
as I can tell, there are no missing dependencies.
