[Evolution] Evolution 1.4.5 Crash on Summary

[jib <jib2 libertysurf fr>]

[Mandrake 9.1]
I just upgraded from 1.2.2 to 1.4.5 (rpm from ximian-mdk 9.1) and every time i try to go on Summary, evolution will
crash. I can still open Summary in a new window. I have no problems with other features.

I tried to start evolution from a terminal and i got Bonobo-critical and Gtk-Critical msg.
It doesn't seem to be a default browser related problem, since Mozilla will open when i click on a link.
(i did the Guenther's trick about default browser in gnome-control-center).

Here is what i get on terminal :

jb localhost jb]$ evolution
