"ASSERTION: character/glyph clump contains no glyphs!"
###!!! ASSERTION: character/glyph clump contains no glyphs!: 'glyphStart < glyphEnd', file /Users/jruderman/mozilla-central/gfx/thebes/src/gfxCoreTextFonts.cpp, line 733 ###!!! ASSERTION: character/glyph contains no characters!: 'charStart != charEnd', file /Users/jruderman/mozilla-central/gfx/thebes/src/gfxCoreTextFonts.cpp, line 734 This is either a recent regression in Gecko or a regression from the recent Snow Leopard security update.
The problem was a result of a hack in the Core Text code, intended to work around an issue with direction override codes (because Core Text deletes the glyphs corresponding to direction overrides, it can look as though those characters have formed ligatures). A better solution than an ad-hoc index adjustment for that issue is to include spaces to separate the overrides from the "real" text content, as we used to do in the ATSUI code as well.
