This particular bug is actually a different problem in XCB
(https://bugs.freedesktop.org/show_bug.cgi?id=40372 ,
http://cgit.freedesktop.org/xcb/libxcb/commit/?id=5ceeaaa4294201b3f613c07f9ec610c0e5f673c7).
 I also ran into this bug since I started with an old libxcb.  As a result I
discovered that it's easy to upgrade libxcb independent of the rest of X11, so
we could try and convince the distros to push libxcb 1.9 to older releases. 
I'm not sure what the best option is to help people out wrt. them running into
issues with older releases, I'm sure you have much more experience dealing with
that then I do.
