--- Comment #5 from Tim Holy holy@wustl.edu 2009-05-30 04:54:31 --- There is a patch available: for the final version, see http://marc.info/?l=wine-patches&m=122805886523427&w=2
I don't know of any reason this couldn't be applied to the source tree. (It wasn't sufficient to fix my problem because of another error with the application. But at least this patch seems to work properly.)
