same problem.  the attachment is successfully opened but sup thinks it
failed and sup displays it as text.

nope, just the exact two lines you supplied above.

I wonder if the problem is that system isn't correctly understanding
the return value from open?  

tangerine:~>open K.png
tangerine:~>echo $?
0

hmmm, I would think 0 is the expected success value?  How could I reverse
true and false?  I'm curious to try that but 
! $?.success? 
$?.success?true:false 
don't work, they error out and sup defaults to run-mailcap.
