Package: libx11-6
Version: 2:1.8.13-1
Severity: normal

A 19-year-old NEWS.Debian file has been added in this version:

   /usr/share/doc/libx11-6/NEWS.Debian.gz

which contains

libx11 (2:1.1-1) experimental; urgency=low

   [ Josh Triplett, Jamey Sharp ]
   libx11 1.1 includes our work on Xlib/XCB, which uses XCB as the Xlib
   transport layer, and allows a client to use both Xlib and XCB on the
   same connection. This allows clients to transition from Xlib to XCB
   incrementally.  libx11-6 1.1 is API- and ABI-compatible with previous
   versions, and does not require any software or package changes.

   Ideally, you will not notice any
   change at all.  However, Xlib/XCB includes some additional
   code to check for bugs in calling software.  If you encounter a problem, you
   will most likely just see an application disappear, due to having triggered
   an assertion and aborted.  If you ran the application from a terminal, you
   can look there to see error output and get more details; otherwise, look at
   ~/.xsession-errors.  These assertions look like one of these:

     xcb_xlib.c:41: xcb_xlib_lock: Assertion `!c->xlib.lock' failed.
     xcb_xlib.c:50: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.

   Both of these represent bugs in a caller of libX11, and *not* in
   libX11 or libxcb.  The first assertion means that a caller attempted
   to lock the display while already locked.  The second assertion means
   that a caller attempted to unlock the display without having it
   locked.  If you encounter such bugs, please report a bug against the
   offending software (*not* libx11-6 or libxcb), provide a backtrace,
   and X-Debbugs-CC: [email protected] if you need help tracking
   down the problem.  If the bug always consistently occurs when running
   the application (or in the case of a library, invoking the library),
   use severity "important", and raise to "grave" after the etch release.

This is confusing. It applied to libx11 1.1, but the current version
is 1.8.13.

What do you mean by "added"? It hasn't been touched since 2008.

If you saw it only now, then it must be due to something else.
