I figured out the cause of my major woes tonight: bug 388267. I have a workaround, so I'm back to hacking on Verbosio's trunk.
Also, our good friend Boris Zbarsky lent a hand debugging bug 388254, which is really very noisy in Verbosio. We believe that bug 388255 is a direct result of it, too. As for bug 388264, that is likely a duplicate bug, but no one's checked that yet.
That accounts for all the bugs I filed as a result of my Verbosio snapshot a few days ago. I'm a happy coder.
Though also a bit lazy:
