Hello, I managed to produce this error from within Taverna. My hunch is that 
this is a
cosequence of difficulties that other parts of Taverna have with the "merge" of 
ports and
about what to delete (internally) after a merge was deleted. But whatever may 
have caused it,
this error should not happen, I presume.

Taverna shows the processors and links, all correct from what I could see, but 
no image is
derived from it. To save this list from a long attachment and to test if that 
other parse
could work with this,  I uploaded the workflow that is reliably causing this 
problem to

http://www.myexperiment.org/workflows/856

I have not tested if the workflow can be executed.

Thanks and regards,

Steffen (still whining since he does not have a backup with a working version)
