--- Comment #16 from jbh@alchemy.lu 2013-03-21 04:32:46 CDT --- Beh, I'm actually the reason it was removed for 1.5.23... Supposedly it had been worked around in wine, and I bothered the packager to remove the fix from the archlinux build script. Sorry for the noise!
On the other hand afaik this still ought to be fixed in wine itself, so something must be wrong with the fix in wine itself.
