What I was doing when the application crashed:
On Desktop 1, Akgregator was pulling in items after importing a large OPML file from Google Reader. I was working in OpenOffice on Desktop 4, and switched to Desktop 1 to check on its progress. When I switched back to Desktop 4 (using Ctrl-F4), Kontact crashed.
