--- Comment #3 from Rafał Mużyło galtgendo@o2.pl --- That backtrace has likely very little to do with text corruption. It's likely simply because this bug was opened after bug 42381 was closed and the reporter attached the old backtrace.
Though, while still unrelated to the text problem, there *is* some major raciness either in the app or wine (hard to tell one way or another) wrt. setting the language. Not sure if it's related to that, but crashes on startup happen too.
That raciness problem is that if you manually set the language to 7 (Japanese) sometimes it gets correctly set and sometimes it doesn't (checked as a curio). Though it just might be that the executable doesn't fully support CJK, even though the required resources are present. (yet, I still think it should be deterministic, not random)
Still let's try to see if there's a proper fix for the text first.
