But in wine 0.90 there was no crashes at all! And now they appears too frequently.
Probably wine is getting more and more NT compliant, thus some tricks meant to emulate Win9x [better] have been removed. Anyway it's a wild guesstimate.
If you are a hundred percent sure this bug wasn't present in Wine 0.9.0, find a regression using bisect. It's not really difficult, I'd say it's quite simple.
Good luck.
