Patch submitted for this bug in tghe patchset starting http://www.winehq.org/pipermail/wine-patches/2010-September/092915.html
Patch set failed on WinNT4 so reworking slightly, but fixes for this defect are included in it.
If your patches still apply, you could try to submit them on wine-devel for review.
