Fix for bug #33295
2002-12-07 Jeffrey Stedfast <fejj@ximian.com> Fix for bug #33295 * e-msg-composer-attachment.c: Change the parent_class to a GObjectClass pointer instead of a GtkObjectClass pointer. (e_msg_composer_attachment_edit): Ref the attachment object so that if the attachment is removed while it is still being edited, the attachment object will still exist and therefor foil the user's attempt to make Evolution crash when they close the properties dialog for this attachment. (close_cb): Unref the attachment object. svn path=/trunk/; revision=19053
