I didn't scrap anything. I'm saying more like I am unable to do any
testing or comparison if things are broken for me with and without
your change. I'm telling it here so that you or anyone else could help
me figure out what is going on.

What I mean by "doesn't work" is that the media in question gets
automatically mounted and I get the dialog "Open with Files". Somehow
the udev rule never get triggered AFAICT:

 $ osinfo-detect -f env /dev/sdb1
OSINFO_BOOTABLE=1
OSINFO_INSTALLER=http://fedoraproject.org/fedora/18
OSINFO_LIVE=http://fedoraproject.org/fedora/18
OSINFO_MEDIA=http://fedoraproject.org/fedora/18:3
$ udevadm info --query=all /dev/sdb1|grep OSI
$

$ osinfo-detect -f env /dev/loop5p1
OSINFO_BOOTABLE=1
OSINFO_INSTALLER=http://fedoraproject.org/fedora/17
OSINFO_MEDIA=http://fedoraproject.org/fedora/17:1
$ udevadm info --query=all /dev/loop5p1|grep OSI

Great! If you have also tested against USB stick and hw CDROM, thats
all the testing we need.

In any case, I have no objection on pushing this change already as I
haven't seen it to cause any regressions.
