Bugs going away for no apparent reason is never good. I can pinpoint the versions around which the bug appeared as well as the versions in which it disappeared. And there's nothing obvious in either diff. Bleah. Oh well, just have to keep an eye on it to see if it comes back.
Made some decent progress. Now I'm updating my laptop and building some new unstable stuff to play with like epiphany, gtk2 emacs, and updating my evolution build.
