Unset the GValue after we're done using what it contained.

2004-03-03  Christian Persch  <chpe@cvs.gnome.org>

	* embed/downloader-view.c: (download_dialog_pause_cb),
	(download_dialog_abort_cb):

	Unset the GValue after we're done using what it contained.

	* embed/mozilla/MozDownload.cpp:

	Weak ref mEphyDownload, and assert that is has been finalised by the time
	we get to ~MozDownload.

	* embed/mozilla/mozilla-download.cpp:

	Debug output in _init and _finalize.
