Bug#636099: Setting keybindings in a _list key makes metacity fail to start

[Josh Triplett]

Package: metacity
Version: 1:2.34.1-1
Severity: important

(Severity important because fixing the problem proves non-trivial when
the usual X environment won't start.)

In the course of bug 635970, I discovered the metacity functionality for
setting multiple keybindings for a particular function, by creating a
gconf key suffixed with _list containing a string for each keybinding.
I added a key /apps/metacity/window_keybindings/close_list, as a list
containing the string <Super>c, and it worked during that session.
However, the next time I attempted to log in, metacity failed to start.
(GNOME did not provide any useful feedback about that, either, but I'll
report that as a separate bug.)  ~/.xsession-errors contained:

(metacity:3041): GConf-CRITICAL **: gconf_value_get_string: assertion `value->type == GCONF_VALUE_STRING' failed
gnome-session[2967]: WARNING: Application 'gnome-wm.desktop' failed to register before timeout
