Just after installing a fully fresh Ubuntu 9.10, I changed the Theme to be "New wave". After some time, I tried to open F-Spot for first time, and crash, same error as Roussillon's.
I change the theme back to default "Human", started F-Spot and voilà, it worked.
I changed the theme again to "New wave", and re-voilà, it also works now...
Not quite familiar with mono-based stuff, so can't tell why I got it solved just changing the Theme...
