Nothing changed in wine-1.3.9-325-gfea5767.
Try this patch: http://www.winehq.org/pipermail/wine-patches/2010-December/097150.html
The installer will tell you that's installing the app instead of removing it, which is another bug. It does remove the files but leaves a number of empty directories behind, which is another bug.
And the entry under the Uninstall key is not removed, nor is the cached local package deleted, which is yet another bug.
It is exactly as you say. Should I report these issues as separate bugs?
