System.DllNotFoundException: /usr/lib/tomboy/libtomboy.so

Binary package hint: tomboy

Tomboy isn't working for me in oneiric. It's easiest to get a stack trace by just doing the following:

tomboy --new-note

Which gives the following trace:

====
Exception in Gtk# callback delegate
  Note: Applications can use GLib.ExceptionManager.UnhandledException to handle the exception.
System.Exception: System.DllNotFoundException: /usr/lib/tomboy/libtomboy.so

Server stack trace:

Exception rethrown at [0]:

You can get other traces by doing different things once tomboy's applet is running, but they all complain about the missing dll.
