--- Comment #2 from Sebastian Lackner sebastian@fds-team.de --- Thanks for the bug report. I am not aware of any FreeBSD specific patches, so it will require a bit effort to track down this issue. Please try to collect a log with WINEDEBUG=+relay, this will probably give a hint what is going wrong. You might have to compress the log or upload it somewhere else when its too big for bugzilla.
If you do not hesitate to build wine from source, it would help to a bisect in the set of staging patches. If you want to give this idea try, feel free to ping me in #wine-staging where I can explain all the details.
