Subject: [PATCH] Fix crash when clicking on the canvas while un/loading a
 session.

GTK events are still handled while un/loading a session (e.g display
"Loading" message or showing the splash triggers an event-loop run).
Global canvas elements (e.g. Rulers) may respond to session-specific
actions.
