In converting a PyQt4 program to PyQt5 I ran into an error because under
PyQt5 (5.2), QFileDialog.getOpenFileName() returns a tuple of two strings.
The first is either a path or null depending on the Cancel button, and the
second always null.

According to the C++ doc for getOpenFileName [1], the returned value is a
string, and "If the user presses Cancel, it returns a null string." In the
PyQt4 doc [2] it shows getOpenFileName returning a string (although it
mentions that the three get...Filter methods return tuples).

Was the behavior of getOpenFileName changed deliberately or is this a bug?

Thanks,
Dave Cortesi
