Subject: [PATCH] Take a reference on the gio file monitors while signaling
 pending file changes

It was possible for a signal handler to remove the last reference and
dispose the monitor.  If there were remaining pending_file_changes they
tried to dereference the disposed monitor.

This patch simply calls g_object_{ref,unref} around the loop that signals
the changes.
