Lost task and memo window in Evolution

[Robert Hodgins <ehodgins@telusplanet.net>]

I'm running Evolution 2.22.3.1 on Debian Lenny.

While I was using the calendar, Evolution crashed. When I restarted it,
the memo and task lists were blank.

The relevant files are still present. (For
example, .evolution/memos/local/system/journal.ics is still on the hard
drive.) Any hints or links that will help me make the memo and task list
visible again?
