I'm afraid I can't help. And indeed, we do not encourage using
libxcb-property, which will disappear soon.

Anyhow, if it *really* hangs in xcb_property_changed() there might be a
serious bug, because that function is just used to pass a PropertyNotify
event received to a call-back function. So there's no read on the wire as
this stage of the code.
So since the code is rather simple, and unless it goes in a endless
loop, I'd say that the back-trace and the fact that it hangs in
xcb_property_changed might be irrelevant.

My 2¢,
