Hi Christian,
	We have an open ticket (#8515) in our bug-tracking system for this,  
but I don't see any activity for it since it was opened.  The  
developer that works on that code is gone for a week and I don't see  
any simple fix for the problem myself.  If you feel comfortable  
editing the Chimera Python source code, you could make a small change  
to <your Chimera installation>/share/DNPuppet/__init__.py that might  
allow you to get work done.  Lines 450 and 451 should look like this:

       else:
           keyfile = self.getWebFile('w')

If you edit them to put a 'return' statement between them, like this:

       else:
           return
           keyfile = self.getWebFile('w')

then I think Chimera will work, though it might have trouble opening  
Chimera scripts from web pages if you do any of that.
	I will add you to the recipient list for the open ticket so you get a  
notification when a real fix occurs.
