Tomboy was working fine until I installed Lion.  Once I installed Lion, every time I run Tomboy it crashes.  I upgraded Tomboy and Mono to the latest versions (Tomboy v. 1.5.2 and Mono v. 2.10.5).  Now when I run Tomboy from the console, I get:

(Tomboy:20078): Gtk-WARNING **: Could not find the icon 'note-new'. The 'hicolor' theme
was not found either, perhaps you need to install it.
You can get a copy from:

It also always crashes if I run it from the GUI.
