+Tue Dec  3 12:12:18 UTC 2013
+libgksu doesn't work anymore on Slackware 14.1 (and eventually -Current).

+are no longer maintained upstream. We will probably drop this in future
+releases. This will also effect mate-file-manager-gksu.

 the directories in Firefox.  Fixes for this have been committed to xdg-utils
-package, but we must set the xdg-mime entries manually.

+add some xdg-mime default handlers.

+Then, as your regular user, first back up the following file:
 $HOME/.local/share/applications/defaults.list and then enter the next two
 commands in a terminal to set the default handler:
