"no styles available in family" on Firefox debug build

[Zeno]

I'm trying to get a debug build running of Firefox, so I got a pre-compiled from ftp://ftp.mozilla.org/pub/firefox/tinde ... taller.exe

It runs okay, but when I try to visit any website I get a crash:

###!!! ASSERTION: no styles available in family "Fette Engschrift":
'mAvailableF onts.Length() != 0', file e:/builds/moz2_slave/mozilla-central-win32-debug/build/gfx/thebes/src/gfxWindowsFonts.cpp, line 289

Any ideas?

If a font "Fette Engshrift" is not broken, it seems a bug, as is often the case with nightly builds.

Where can I get a more stable debug build? I'm getting assertion errors all over the place.

In short, nowhere. Even release builds say "Assertion!" ! Probably developers should not use NS_Assertion so frequently as they do now. But who is going to fix them? At a glance, it's hard to judge NS_Assertion is rightly used, or it should be replaced with other message functions. In my opinion, browser should not assert even when 1 or 2 fonts are broken, though we need to know there's some problem with loading fonts, in some way or other way. In this case, it is NS_Assertion.
