Toolbar icons non-deterministic?
There appears to be something strange going on with the toolbar buttons in TBB still. I think it may be related to either updates or intitialization errors. It seems like sometimes you can install a fresh TBB and just get either no toolbar buttons or just a subset. Whatever you get after the first run seems to become stable thereafter.
We need to investigate more. This probably means launching and them rm'ing TBB multiple times and watching the error console, Torbutton logs, and other logs.. Fun.
