Hi.
What is the upstream status on this? after some quick research, it seems
that it has been originally developed by Kevin Kofler and is published
in the fedora bugtracker at
https://bugzilla.redhat.com/show_bug.cgi?id=450450
I'll add that url to the patch file in a minute.
However I fail to find the upstream discussion on that patch. Is that
patch being considered at all upstream?
it seems that also ubuntu is affected pretty badly about this patch.
