Muon crash

[Phil]

Muon is crashing after a recent set of updates including Muon itself. Is 
this known problem?

Also, I'd like to install Skype but apt-get fails with the follow error 
message:

phil at Asus:~$ sudo apt-get install skype
Reading package lists... Error!
E: Encountered a section with no Package: header
E: Problem with MergeList 
/var/lib/apt/lists/au.archive.ubuntu.com_ubuntu_dists_raring_main_i18n_Translation-en
E: The package lists or status file could not be parsed or opened.

Is there a work-around?
