That's quite plausible; I'll look into it. Leaving ni? on myself for now...
The assertion here seems to indicate that we're calling nsPresContext::GetDefaultFont for a language that we haven't previously handled, and so its prefs aren't pre-cached in StaticPresData; but AFAICS, that would have behaved in the same way either before or after bug 734008.

Looking again at the patch in bug 734008, I don't see why it would have changed anything in such a way as to cause this. (I tried re-triggering the failed test run a bunch of times, and it didn't happen again, suggesting it's a fairly rare intermittent; and as such, it's difficult to pinpoint a regressing patch.)

In bug 734008, the call to gfxPlatformFontList::PlatformFontList()->InitLangService() was removed from ServoStyleSet::Init(), but all that call did was to ensure the languageAtomService is created and the mLangService pointer in PlatformFontList was set. That's unnecessary because it is now done already by the gfxPlatformFontList constructor.
