Log:
2008-02-14  Sven Neumann  <sven gimp org>

	* gap/gap_pview_da.c (gap_pview_set_size): added a sanity check
	for the preview size.

	* gap/gap_mov_dialog.c (mov_path_prevw_create)
	(mov_pview_size_allocate_callback)
	* gap/gap_player_dialog.c (p_update_pviewsize): make sure that the
	preview size doesn't become zero. Fixes bug #516443.
