I am by no means qualified to tell whether your DOTA crash is related to this
bug, but because others think it is, I am curious to know when / whether it's
fixed ;)

I think what is happening is that a separate bug is in the process of being
unearthed, and that changes to wine may be forthcoming which may address your
issue.  (See Henri's post above yours, and Ken's below).  Essentially, there
were upstream bugs which were fixed in libxcb, but now there appear to be
problems in wine itself which cause similar symptoms.

Testing whether this is so may require applying a patch to wine once fixes are
available (or, alternately, waiting for a release of wine which includes
fixes).

So, if you are willing, I would encourage you to wait a bit for more fixes ...
if you need help applying patches, feel free to write me and I will try to walk
you through it.  

Sorry if I'm telling you things you already know ... I don't recognize all the
users here ... just trying to encourage any user with this kind of bug to
re-test when it's believed truly fixed, and willing to offer help with that if
it's needed.

Cheers.
