f-spot on Fedora 17 doesn't start

["Dave Sill" <f-spot dave sill org>]

I'm a long-time f-spot user. Recently reinstalled my desktop system
and now f-spot doesn't start. I've installed the package
f-spot-0.8.2-6.fc17.x86_64.rpm.

Here's what happens:

[Info  10:49:05.668] Initializing Mono.Addins

I'm running KDE.

Any ideas?
