No time right now to make a real good repro...but here's the output I saw.  Originally I had Tomboy installed in /home/sandy/stage/tomboy, and had been running 0.9.8-ish from there.  Then I removed my package-installed Tomboy from /usr and installed 0.10.0-ish there.  When I ran Tomboy, it crashed.  When I tried running again, it succeeded.  Enabled/disabled plugins were properly remembered.

The first chunk of output is from the run that crashed.  The second chunk of output is from the following run, which succeeded.
