** Fixes bug #311042, Patch by Milan Crha
2008-05-14 Matthew Barnes <mbarnes@redhat.com> ** Fixes bug #311042, Patch by Milan Crha * widgets/misc/e-info-label.c: (el_size_allocate), (el_class_init), (e_info_label_set_info), (get_text_full_width): Allocate size for location and info labels differently, than GtkHBox does, to be able to minimize it as much as possible and do not waste empty space. svn path=/trunk/; revision=35499
