Please explain how it's invalid - that is, where the problem actually lies - so
that I know what to report to my distro.

As I said in the original report, although the problem did manifest on updating
both libxcb and the fglrx drivers, all information I have found online claims
that past occurrences of this error message have been due not to a bug in
either of them but to one in the application calling libxcb. In this case, that
would appear to be Wine, specifically libopengl32.dll. Is that not the case? If
so, what *is* actually going on?
