--- Comment #16 from Michael Karcher <wine at mkarcher.dialup.fu-berlin.de>  2008-08-18 16:51:48 ---
The patches linked here fix the symptom, but not the cause. Wine crashes
because there are invalid glyph indices in an ExtTextOutW with ETO_GLYPH_INDEX.
The log shows many working ExtTextOuts, where the indices are well below 256,
and the crashing one with indices that all have their *low* byte zero.

Probably there are two bugs to fix: Wine should not crash on bad glyph indices
(symptom), and also Firefox should not provide bad glyph indices at all
(cause). Wether the latter is a Firefox or a Wine bug is yet to be determined.
