Geoff Jacobsen has the same problem in bug #36532.
He was able to solve the issue by reinstalling gs-esp with following commands:
$ sudo dpkg --purge --force-all gs-esp $ sudo apt-get install gs-esp
Then you can add the comment in mime.convs again: #application/vnd.cups-postscript application/vnd.cups-raster 100 pstoraster
You only need gs-esp, you can safely remove gs-afpl and gs-gpl with following command: $ sudo apt-get --purge remove gs-afpl gs-gpl
