Comment 1 for bug 1221330

This bug also affects me on a fresh install of Linux Mint 14 MATE on a Dell e6400 laptop, having previously been used in LM13. In my case I get the following error when trying to mount any external drives or USB stick:

>
Error mounting /dev/sr0 at /media/~/Linux Mint 13 MATE 64-bit: Command-line `mount -t "iso9660" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,iocharset=utf8,mode=0400,dmode=0500" "/dev/sr0" "/media/~/Linux Mint 13 MATE 64-bit"' exited with non-zero exit status 32: mount: unknown filesystem type 'iso9660'
