Comment:

 This doesn't block 4.5-alpha-1. That ship has sailed, and we need to
 exercise the updater anyway. However, we should fix this ASAP for 4.0.1
 and 4.5-alpha-1.

 We've been wanting to move this functionality out of Torbutton and into
 C++ for some time now. Maybe now is the time?

 We should also protect this with a unittest, as this is not the first time
 this has broken, and with the new HTTP cache due in FF38ESR, it won't be
 the last.
