Why am I unable to open my Simulink model from the File -> Open Menu?

When I try to open my SIMULINK models from the File -> Open Menu I get the following error message:

 Error:  Simulink model open was called with too few arguments.

I can still open my models from the MATLAB Command Window using the OPEN_SYSTEM command.

This behavior occurs when your model has the same name as another file, function, or model on the MATLAB path.

You can determine this using the WHICH command:

which -all modelname

Currently, to work around this issue, you will need to rename your model with a name that does not exist on the MATLAB path.
