It's possible that this is not wine bug at all then. Application bug that they fixed later version. Without testing in windows or finding the cause it's hard to say. Do you mind testing newer wine?
It is possible it was a Total Commander bug, I can't test the app on Windows unfortunately. Feel free to close, the bug does not appear in the new versions anyway.
