Comment 29 for bug 408016

Made a tiny bit more progress, trying to get upstream wine bug re-opened but they want to fob the blame onto X11 and ignore their own problems, so chance of a quick solution is unlikely.

Summary of the wine problem as far as I can tell: badly behaved win32 exe programs will call CreateFontIndirect() with bogus parameters and somehow under real Microsoft Win-XP these programs actually work. Under wine the bogus parameters gumby up the font metric calculator, which in turn cranks the handle on the X11 drivers -- whole lot of code, not many error checks.

Getting X11 fixed might be a good step towards getting other buggy applications fixed, then they can stop trying to blame everything on the X server!

I'll be patching up my own version of wine but I hesitate to post any public patch because it is rather a delicate matter to deal with badly behaved exe programs in a way that maintains maximum Microsoft compatibility. Doing the job right requires excellent understanding of how the win32 fonts work and a bit of research into how Microsoft deal with the questionable cases.

I've gone about as far as I can go with this so I would appreciate someone pushing my NULL pointer check into the X server code and close off this bug. Thanks.
