That fix works for your particular project setup. But what happens, if the 
custom widget is not below the directory of the file in question but 
somewhere else. In order to have it work more generally, we might have to 
introduce some conventions. Following is the proposal.

1. I'll include the os.chdir solution proposed by you. This allows the custom 
widgets to be placed somewhere below the directory of the dialog.
2. I'll add the project directory (project.ppath) to the PYTHONPATH 
environment variable. That makes custom widgets below the project directory 
available.

And this defines the convention. Custom widgets must be accessible either from 
the project directory or below the dialog in question.

Would this proposal be ok?
