[PyQt] stand alone QFileDialog

[Detlev Offenbach]

Hello Janwillem,

there is nothing wrong with your setup. It is caused by a bug which was 
undiscovered for years. Congratulations :-))

It has been fixed for all eric4 variants and eric5 5.1 and pushed to the 
sourcecode repo. It will be included in the next releases.
