Getting rid of GTK warnings on Emacs 24.1

I recently upgraded to Emacs 24.1 and from the terminal I’ve been getting a ton of errors like so:

Gtk-Message: Failed to load module “canberra-gtk-module”
`menu_proxy_module_load’: emacs: undefined symbol: menu_proxy_module_load

(emacs:17803): Gtk-WARNING **: Failed to load type module: (null)

`menu_proxy_module_load’: emacs: undefined symbol: menu_proxy_module_load

(emacs:17803): Gtk-WARNING **: Failed to load type module: (null)

`menu_proxy_module_load’: emacs: undefined symbol: menu_proxy_module_load

(emacs:17803): Gtk-WARNING **: Failed to load type module: (null)

etc…

Turns out there are a couple of environment variables you can unset in .bashrc to fix this.

export UBUNTU_MENUPROXY=
export GTK_MODULES=

I’ve got no idea what these are for but appears to do the job and I can now start up without seeing a page full of warnings.
