Cannot edit blocks on dashboard pages

f58d421 seems to be the relevant Context commit. I'd like to fix this, but I'm afraid I don't quite grep the whole Spaces/Context/CTools/etc stack well enough to know where to start yet.

Hello? Anyone out there?

Well, here's a thing. Funny how hours of code-tracing and head-bashing can result in the tiniest of patches. It's probably wrong anyway, though; I presume I should be using context_reaction_block::editable_region() somehow, but I can't make out how. Also, regions which don't already have blocks in them still do not appear for block droppage, though that might be a different bug.

Note that in addition to this, the theme needs to have a "layouts" section in the .info file - see context_layout's README.txt. I just used hook_system_info_alter() to patch one into Bartik for now:

/** 
 * Implementation of hook_system_info_alter().
 *
 * Alter Bartik's info so that it has "layout" info.
 */
function spaces_dashboard_system_info_alter(&$info, $file, $type) {
  if ($type === 'theme' && $file->name === 'bartik') {
    $info['layouts'] = array(
      'default' => array(
        'name' => t('Default'),
        'description' => t('Default layout'),
        // Just using 'page' will cause only regions to be rendered because the
        // .tpl file won't be found.
        'template' => 'templates/page',
        'regions' => array_keys($info['regions']),
      ),
    );
  }
}

Derp.
