[compiz] Keybindings trouble

[Jeff Bailes]

    I'm using the latest compiz-git (along with compcomm patches & ccsm)
and I'm having troubles with some keybindings.  It seems that compiz is
somehow intercepting any shortcuts that I try to use that are Control
+Alt+*OTHER*.  For example, I have set in my xfce keyboard settings to
lock the screen on Control+Alt+l, it works fine with xfwm4 and the last
version of beryl, but it only sometimes works with compiz.  And my set
shortcut for xkill (Control+Alt+Escape) doesn't ever work under compiz.
The weird thing is that when I press Control+Alt on their own it acts as
if that's its own keybinding (cursors disappear etc) but there's nothing
set to it (The only thing I could think of is the water plugin, but it's
disabled, and the Initiate key is also disabled.)  Also if I try and add
these shortcuts to the compiz Commands in ccsm it doesn't work either,
though others do work (eg Control+Alt+D for show desktop).
