Delete ("reinitialize"?) your current wineprefix (the place where all Wine stuff + installed apps are stored) by removing ~/.wine. Or set up a clean wineprefix (by adding WINEPREFIX=foldername in front of your wine command). Then run your application. Whatever it outputs now is not related to any DLL overrides (because there aren't any anymore) so you can safely report a bug with the terminal output / crash data you get.
