Comment 10 for bug 377226

Hey!

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=519664#42 suggested a way to fix this issue, and it seems to work for me!
I join the patch that make Listen always inherit at least from object. Not sure of its quality, a review would probably be useful, e.g. to complete it; because I only added "object" parent to classes that didn't inherit at all, not sure there's classes that still miss their object parent.

Regards,
Colomban
