Please attach the output of 'cat /etc/mtab' and 'sudo cat /var/lib/DeviceKit-disks/mtab' after doing this.

The relevant line from /etc/mtab should look like this

 /dev/sr1 /media/Setup iso9660 ro,nosuid,nodev,uhelper=devkit,uid=500,gid=500,iocharset=utf8,mode=0400,dmode=0500 0 0

and the relevant like from the latter like this

 %2Fdev%2Fsr1 %2Fmedia%2FSetup 500 1

It looks like something is wrong because it should definitely include 'uhelper=devkit'.

This doesn't happen on my machine - it just works here. What version of DeviceKit-disks are you running?
