[Evolution] crash on startup

[Francois Schoubben <fsc info fundp ac be>]

Hi,
I've just install Evolution 0.99.2 on a Debian potato machine, and i
have the following message when i try to launch it...
---
evolution-shell-WARNING **: Cannot access Bonobo/ConfigDatabase on
wombat: (IDL:OAF/GeneralError:1.0)
---
Of course, evolution stop just after.
Any idea of how i can correct that?
I installed it by an 
apt-get install evolution
with this line in /etc/atp/source.list
"deb http://red-carpet.ximian.com/debian stable main"
