XCB again

[James Richard Tyrer]

I recompiled XCB and was, therefore, reminded of this problem:

	xcb_xlib.c:50: xcb_xlib_unlock: Assertion c->xlib.lock failed

further research with Google, and I found this:

	http://osdir.com/ml/debian.devel.announce/2006-11/msg00010.html

This clearly states that this is NOT an XCB bug.  IIUC, the problem is 
that KDE 4 is trying to lock it twice, or it is possible that the 
problem is with one of the libraries that KDE 4 is using.

I started a bug for this:

https://bugs.kde.org/show_bug.cgi?id=150519

and the log of my attempt to start kde is available there.
