[Evolution] Unstable evolution (snaphshots)

[fayard clipper ens fr (Francois Fayard)]

Hi,

I've tried the snapshots of evolution  with my potato+ximian
adding to my sources.list:
deb http://spidermonkey.ximian.com/evolution-snapshots/distributions/Debian unstable main

Now I can read my French mails, but when I send a mail (or I want to) I get the window:
Could not create a composer window.

Is it a general problem people have with this snapshots.
I've tried to swith back to the evolution 0.8 with:
apt-get remove evolution
change the sources.list
apt-get update
apt-get install evolution

But now I've got a segfault when evolution starts

Thanks for your help
