Vincent, this patch is not something that I would dare to submit, it's just a blind uneducated guess on how to fix the problem. As I already wrote I don't have enough knowledge of freetype and Wine internals to fix this problem properly, thus I filed a bugreport and CC'ed author of the line in question - is was Dmitry Timoshkov accordingly to git blame output. It seems that he isn't interested in looking at this bug (at least now) as he had removed himself from CC list though.
You may need to have another look at git blame output.
