OS X Technologies :: Automator Workflow Fails With Cryptic Error Message

I'm updating an Automator workflow for OS X Lion that I initally developed and used, without issue, in OS X Tiger. The workflow asks for a name, creates a folder for the name, takes a digital image with a Nikon D50 connected to the computer, and saves the image to the new folder. This aspect of the workflow works fine. 

I then have a prompt asking if we should take another. If the user says "yes," the script should take another image and save it to the folder. This is where I run into an issue. When I attempt to add another "Take a Picture Action" into the workflow, I get the cryptic (at least to me) error message in the attached screenshot.   

Here's the text: 

"Cannot update for observer <AMWorkflow 0x400458ac0> for the key path "parameters.name" from <TakePicture 0x403e3b0a0>, most likely because the value for the key "parameters" has changed without an appropriate KVO notification being sent. Check the KVO-compliance of the TakePicture class." 

The language of this error would seem to indicate a bug.
