 I just had a weird error with TBB 3.0a3 on Linux. According to
 about:cache, my cache was not being isolated with any domain= keys, and I
 wasn't getting any 'SSC" isolation log messages. I restarted a couple
 times and tracked it down to the Torbutton startup-observer.js component
 not loading for some reason, with no exceptions in the log window about
 it. I installed XPCOM viewer to see if it was even registered, and then it
 suddenly started working again after that restart...

 Scary :/.
