Otherwise, you can just run "wineboot -u" yourself for the same effect.
thanks for the hint, I was not aware of this. And yes, my tests show that this would be a suitable workaround. I do not know how I could have figured this out myself.
In any case, a crash shouuld be considered a bug. If some state is not supported, it should be handled gracefully, showing an error message that would help identifying the issue.
At first I thought the problem is with the application because it was starting but crashing only at some later time. It took quite some effort to figure out what the actually problem was. I did not test your patch, but if it fixes this issue, it would be great if it would be included in wine.
