Bug#498642: libx11-6: Locking assertion failure
Package: libx11-6
Version: 2:1.1.4-2
Severity: important
I get the following error on the Console while starting the X-window
system using `startx'.
--------------------------
Locking assertion failure. Backtrace:

------------
Quite often I also notice that the Window manager cannot kill itself during
Exit from X-Window (it sorts of hang there and I need to kill X with
Ctrl-Alt-Backspace) which I do not know can be from the assertion
failure.
However, assertion failure for this package did not happen with Etch and
I am noticing it only after upgrading to Testing.
Since the backtrace shows failure mostly with '/usr/lib/libX11.so.6',
which is part of 'libx11-6', I am filling bug-report against 'libx11-6'.
Note that the xserver driver is 'xserver-xorg-video-intel' and the chip
is Q35.
