When you click in the stack frame, Xamarin Studio is probably trying to
open the corresponding source code file in order to show you where the call was
done.
Since probably you don't have the source code of WinForms installed, it
fails, warning that the file is missing.
Howver, the real problem is the upmost exception which is produced in
SystrayAdd(), which is not implemented.
There are some methods in a few libraries of the mono project which are
not implemented. You can foresee the "problems" (missing methods such as this
one, etc.) using Moma.

Execute this tool on your executables, and study the missing classes
and methods, then try to find a workaround for that missing stuff.

Actually this is a known problem. You can find the corresponding bug in
Ximian, at 2008:
http://lists.ximian.com/pipermail/mono-bugs/2008-October/080810.html
Since it is an error detected in 2008, I wouldn't expect it to be
solved. This leads me to the current status of Winforms, which is deprecated.
This means it is not actually supported by Xamarin.
So, the only solution is not to use NotifyIcon in OS/X. I don't know
whether that's possible in your app. In this case the workaround -if possible-
does not seem to be easy.
Mono has various Gui toolkits available: Gtk#, WinForms...
The only possible solution is what it is described in the page of
toolkits of the mono project, in "alternative implementation approaches":
http://www.mono-project.com/Gui_Toolkits
Separate your application in core and gui. Implement two gui's, one for
Mac and another one for Windows (using your current WinForms module).
For mac, probably the best choice is to use Gtk#.
