gnome-session's "Make CRITICAL warning crash"

Hi,

    Recently we find there are quite a lot of crashes for Evolution 2.5 
running on gnome 2.13.  Now I just find the reason:

http://mail.gnome.org/archives/desktop-devel-list/2005-November/msg00006.html
and
http://cvs.gnome.org/viewcvs/gnome-session/gnome-session/main.c?r1=1.70&r2=1.71

    So now all critical warnings turn to crashes. That is why Jeff Cai 
found 3 crashes when starting Evolution recently. I am not sure whether 
all of us know about this, so just FYI.  I guess there might be more 
crashes. Sorry I didn't noticed this earlier since I was 
running/debuging Evolution 2.5 on gnome 2.12.

       Harry
