Comment 1 for bug 214848

The message itself is harmless, but annoying. See bug #87947, where libxcb was made to use sloppy locks by default for Hardy. Looks like the backtrace still gets printed.

Novell applied more complex patch, which ouputs a warning instead of the backtrace when using sloppy locks : https://bugzilla.novell.com/attachment.cgi?id=182029.
