Bug#439161: gnome-mag: X Window System error on startup

[W. Martin Borgert]

I believe, that this to be upstream bug #452159
(http://bugzilla.gnome.org/show_bug.cgi?id=452159).
It seems to be fixed in SVN rev. 548 on 2007-07-30
(http://svn.gnome.org/viewcvs/gnome-mag?view=revision&revision=548).
Workaround, at least for me: Enable composite extension in
/etc/X11/xorg.conf:

Section "Extensions"
	Option "Composite" "Enable"
EndSection
