groups in roster seems broken
When using groups, gajim acts strangely. If I add 3 contacts (from a transport) to the same group, gajim will display each contact in its own group, but the 3 groups will have the same name. Changing one group's name will change the others, so they are really the same... As I may not be very clear, I'll attach a screenshot. IIRC, the version on 2005-12-01 is working correctly (but I can double check).
I also tried without any config by removing ~/.gajim, but still the same bug.
