** Fix for bug #334675

2007-11-05  Milan Crha  <mcrha@redhat.com>

	** Fix for bug #334675

	* plugins/mail-to-task/mail-to-task.c: (do_mail_to_task), (text_contains_nonwhitespace),
	(get_selected_text), (convert_to_task), (org_gnome_mail_to_task),
	(org_gnome_mail_to_task_menu):
	When selected only one message, then try to use selected text in
	preview as description, instead of whole message body.

	* Requires newer GthHtml (API extended, since revision 8614).

	* mail/em-folder-view.c: (emfv_message_reply): Leak fix.
