Thanks for the info. It's good to see that it's a known issue and that
it's on someones TODO list.

I'm trying to find out whether Survey.dll will be part of the final 1.10
release or if it's only part of the PTR client. I haven't had any luck
so far. I don't know why Blizzard doesn't want to give me this
information, we'll find out sooner or later (eg. the day when they
release 1.10), it just would be nice to know whether the WoW players
need a patch or not.

I'm not very familiar with wine so I probably won't be able to write a
better patch.
