Yeah I'm getting so many err: and fixme: messages that I think I'm gonna try again on the stable release.
If your application is working as expected the debug output can safely be ignored. It is absolutely normal that the output of Wine is very "noisy". On the other hand, if your application is not working as expected in current development and staging versions, it deserves a separate bug report (if the issue has not been reported yet). Our repositories provide packages for all three versions (winehq-stable, winehq-devel and winehq-staging), so doing the necessary tests should be pretty easy.
