* src/ntl-window-msgs.c, src/ntl-window-private.h: Update debugging messages. Allow
synchronous state changes (needed to avoid race conditions), and
don't reset the idle handler if the idle handler is already running.

* src/file-manager/fm-directory-view.c: Include
<libnautilus/libnautilus.h> rather than just
<libnautilus/nautilus-alloc.h> - nitpick in passing.

* src/ntl-uri-map.c: OK, don't check for NULL here, in an attempt to flush out bugs elsewhere.
Let me know of any problems that show up because of this.
