restarted with a clean prefix and this seems to be gone. Apparently something went wrong with the updating of the config after wine was updated. Now, apps cannot find hh.exe anymore, but for the rest the major issue is gone.
I dare to think that the priority should be quite high. Filling the disk in this way for a networked machine serving not just the user who is running wine at the console means almost certain data loss for those who are working from remote. And you discover the workaround only after the data loss.
