[Murray Cumming <murrayc src gnome org>]

commit 28a2d1c534db64b7596141fbeffc2c18b4774731
Author: Murray Cumming <murrayc murrayc com>
Date:   Fri Jul 15 10:13:19 2011 +0200

    ImageGlom: Do not try to get a thumbnail for non-image, non-evince types.
    
    * glom/utility_widgets/imageglom.cc: Just use g_content_type_get_icon(),
    to avoid saving temporary files of huge content, such as video, when just
    navigating through rows.
