The above exception was the direct cause of the following exception:

The status file seems fine, apt is happy with it, this is either a bug in apt-listchanges or a specific FS corruption, but haven't seen that before.

[Julian Andres Klode (juliank)]

The package foliocloudplugin is broken, it was probably written on a Mac - the description ends lines with ^M instead of a newline. (and also does not use a continuation line).

That said, apt-listchanges really ought to use apt_pkg TagFile parser and not hack up its own one.

[Julian Andres Klode (juliank)]

dpkg also probably should validate the contents of that field and clean it up if needed or reject install.
