Console messages per se are not bugs. If everything is working, don't worry about them.
In this case, the message indicates an unclean wineprefix, which would make this bug invalid even if something wasn't working.
Please read https://wiki.winehq.org/Bugs before filing any more bugs.
You were correct about the prefix. Thanks and sorry for wasting your time. This bug can be closed :)
