Solved!
Although it was probably obvious to most of the community.
I discovered that the problem was I needed to encode the
string before I passed it to psd.open().
i.e
file = psd.open (fname.encode (‘utf-8'))
the QFileDialog.getExistingDirectory() return unicode and it needs
to be converted (encoded) into a byte sequence (python string)
to pass to the extension.
Thanks for listening
