-- Information about the crash:
On a clean installation of kubuntu with all updates installed, whilst reading my email in thunderbird I clicked on a http link. There was no default application for http links so I specified /usr/bin/firefox and clicked open. At this point, plasma crashed and restarted itself.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Aborted
