Unable to bind hide_window key, another instance/window has it.

Opening a second terminal window is blocked. To reproduce from the Ratpoison window manager, type "c-t !" to run a script that contains:

$ terminator $geometry --command="screen -S full -c $configfile"

That launches fine, but within that screen session run "sudo -iu root" followed by:

$ terminator --command='/usr/bin/screen -c $configforroot'

It cannot open a new window. It says:

ConfigBase::load: Unable to open /etc/xdg/terminator/config ([Errno 2] No such file or directory: '/etc/xdg/terminator/config')
Unable to connect to DBUS Server, proceeding as standalone

** (terminator:2367): WARNING **: 14:17:48.988: Binding '<Control><Alt>a' failed!
Unable to bind hide_window key, another instance/window has it.

This happens with version Terminator versoin 2.1.0 in the Ratpoison window manager. Untested on Gnome.
