update-manager crashed with Package liblivemedia61 isn't available in _show_transaction()

[Till Kamppeter]

I discovered a still open Software Updater window which was probably open and overlooked for days and clicked "Install". As it seems that some of the listed packages received further updates in the mean time the listed versions were not on the server any more. I got an error message about a missing package and the Updater closed, without giving the possibility to reload the package list. Shortly after, the crash report popped up.
