--- Comment #3 from thomas.belau@gmx.de 2010-09-10 19:08:05 CDT --- Wine loads the font cache on each start. When the chache is discarded on any error it is rebuilded. So there is not a special (Windooze-)app that causes the bug. It depends on the installed fonts.
Take any TTF, let run mkfontscale and each font with "...-0-0-0-0-x-..." (the usual case) causes the bug.
