Crash while trying to view changelog (Unhandled exception ... MyCache.get_changelog )

[Sitsofe Wheeler]

Binary package hint: update-manager

Description of the problem:
Starting update manager and then waiting for the changelog to appear results in either a crash or a python stack on the terminal that update manager was launched from.

Steps to reproduce:
1. Start gnome-terminal .
2. In the gnome-terminal run update-manager .
3. Wait for one minute.

Expected results:
Changelog to appear or message to be presented saying changelog could not be found, try again later or visit this launchpad URL to see the launchpad changelog.

Actual results:
apport pops up or the following is printed on the terminal:
$ update-manager
current dist not found in meta-release file
Unhandled exception in thread started by <bound method MyCache.get_changelog of <UpdateManager.UpdateManager.MyCache object at 0x84d920c>>
