Thunderbird doesn't show message count on launcher icon and does not affect messaging indicator after update to Precise.

[Tobia Tesan]

Thunderbird doesn't show message count on launcher icon and does not affect messaging indicator after update to Precise (icon stays grey, menu doesn't tell me anything). Popup notifications on new message work, though.
Tried uninstalling and reinstalling thunderbird and indicator-messages, removing ~/.thunderbird and creating a new system account altogether, without any success.
I think right after updating a crash was reported about telepathy, but I didn't pay too much attention.
