Subject: Bug#50768: python-imaging: Image.Image.show() blows up
Date: Sun, 21 Nov 1999 00:00:36 +0200

Package: python-imaging
Version: 1.0.1-0pre2
Severity: normal

for some reason _showxv passes None as format to _dump,
and that results in the file = file + "." + format line blowing up.

this fixed it for me.
