UPDATE:
I got my hands on another machine that was updated to Raring..
Clicking ANY of the items that have vanished from the repo causes the crash.
Attempt to select them via keyboard also produces the same crash.
These items (by their nature) are only found in the Status->Not Installed (residual config)
Clicking the rest (those have a nonblank "latest version" and "description") is fine.
