Keyboard shortcut don't work on 0.7.2

[jmatsushita]

Things seem to work when using the plugin from the command menu but the keyboard shortcut don't work. In addition I sometimes see the following error in the console (when using navigate down or up).

Invalid behavior: :lt.objs.sidebar.command/exec-command

I'm seeing this too on a build of the latest LT source too.

I see this on 0.7.2 as well.
