Bisecting the hourlys for Android shows that:

Fails: http://ftp.mozilla.org/pub/mozilla.org/mobile/tinderbox-builds/mozilla-central-android-r7/1285740319/

The guilty changeset is most likely:

Might be bug 600163. Michael Wu says the about:home crash/hang is fixed by the patch in the bug.

I'll take this. I believe it is fixed by 600163, though it is hard to tell from the comments. The more general bug is that the Fennec automated tests don't cover about:home. I'll be fixing that here, in some way.

about:config crashes as well.

This WFM now that a nightly has been respun, approximately 6 hours after I filed the bug for it. The Fennec testing situation is worse than I thought, so there's no point in keeping a blocker bug open for it.

I also tried about:config. It didn't scroll right, but it didn't crash, so I'm assuming that could be existing breakage. I navigated to some other pages afterwards and things seemed ok.
