We have setup a very simple approval workflow for a certain type of content. However, for some reason, the first manual activity couldn't be finished and thus, workflow being blocked.
Any attempt to finish the activity will prompt this error:
An item with the same key has already been added.
Unable to finish the Workflow Activity (tcm:x-xxxxx-xxxxxx)
Here's the data I'm working with (truncated for readability):

Notice that I am reusing the same email-icon image for [mailImage] attribute. I'm inclined to think that this is causing the error because it's the only duplicated component link in the list.
If I remove the mail image component links and finish the activity, it works and I can proceed with the workflow. Odd huh?
I don't see any reason why I can't reuse component links in the same component in regard of workflows being able to proceed. I mean, CMS allowed me to save the component, why not allow me to proceed with Workflow?
EDIT: By the way, this is the error from the Event Logs:
Unable to finish the Workflow Activity (tcm:5-18430-131104)

THe problem you have is because of your auditing template. It might be the case that you have old (pre 2011) VBScript template as your auditing template. Try switching auditing off, or change auditing templates values in properties of your publication
