Nokia’s Maemo-Team seems to be using Bugzilla primarily as a tool to collect hints where they should improve the firmware. Would be nice if they would comment on Bugzilla more often, though.
So submit your bugs and enhancement requests, but please make sure that noone else already did! And vote for those you want fixed!
Here are my favourites. Vote for my bugs, please!
