After the upgrade to 10.10 tomboy crashes at start

Every time I run tomboy it crashes. Here is the message I receive when I start it from the command line (I have removed the publickeytoken just in case it was sensitive information...):

Missing method SetSourcePackageName in assembly /usr/lib/tomboy/Tomboy.exe, type LaunchpadIntegration.LaunchpadIntegration
