(as indicated my moroquendo on Gimp-chat)
Edit:
the bottom line for those who read this post is this:
1. if you have Gimp 2.8.20 and you want to use python filters with a parameter which asks you to select a directory, this will cause a pythonw crash
2. if you are able to edit the python filter in error, follow stackoverflow indications to fix it
3. if you aren't, you have to wait for a fix, either general (from Gimp) or specific (from filter's author)
