Hi alessandro,

you could post the code of your plugin, then it would be easier to
identify your bug. It sound as if a File object is expected somewhere
but None is returned and the basename function fails.

Does the preview function display your plot correctly? I get the same
exception (with the gnu_r_plugin), when I enter incorrect R code, press
OK and close the following 'An error occured...' dialog with yes.

best regards,
 stefan
