[Aurelien Bompard]

Guess what, the first traceback is actually a bug in mailman.client! :-)
There should be a call to self._get_info() in line 634, before the
"return" call, just like with the other properties.
Can you try that and tell me if it fixes it? And if it does, could you
report the bug with the patch to mailman.client on Launchpad?
Thanks.

To fix the second and third tracebacks, please update kittystore from
git, it's a recent commit.

Cheers,
Aurélien

Clean and rebuild dependencies from latest repo revs solves the 
problems...

mailman.client has been patched too.

cheers
