    <para>The <application>libxcb</application> package provides an interface
    to the X Window System protocol, which replaces the current Xlib interface.
    Xlib can also use XCB as a transport layer, allowing software to make
    requests and receive responses with both.</para>

      <para>The <application>libxcb</application> developers have decided
      to be strict in asserting locking bugs in X11 applications. This is
      different than the behavior of <application>libX11</application> when
      used on its own, and it will cause some applications to crash when
      they previously did not. When an application has these types of bugs,
      it will crash with the following assertion:</para>

<screen><literal>xcb_xlib_lock: Assertion `!c->xlib.lock' failed.</literal></screen>

      <para>An environment variable, <envar>LIBXCB_ALLOW_SLOPPY_LOCK</envar>,
      can be set which will allow the locking bugs to not crash the
      application. It is a workaround that is known to be needed in a few
      cases. If it is found that these bugs affect an application in use, add
      the following to your system or personal profile:</para>

<screen><literal>export LIBXCB_ALLOW_SLOPPY_LOCK=1</literal></screen>
