SystemError: E:Type '://ppa.launchpad.net/midori/ppa/ubuntu' is not known on line 2 in source list /etc/apt/sources.list.d/midori-ppa-oneiric.list, E:The list of sources could not be read., E:The package lists or status file could not be parsed or opened.

THis bug report is dues to a configuration erro in your /etc/apt/sources.list.d/midori-ppa-oneiric.list file. It looks like you are missing some leading characters in the line '://ppa.launchped.net' of that file. This is something you will need to resolve manually.

Should it crash? ... or just emit a warning for that line and continue with the rest?
