How to find who linked a bug to a question, when there are multiple users with their display name?

Unfortunately, I don't know any way of finding out through the web. I wouldn't be surprised if the user name was included in one of the X-Launchpad headers.

This seems like a bug (if there isn't already one for it).

That information does not appear to be available in any of the headers either. The entire plain text of the message (with complete original headers) is posted below. Please let me know if I'm missing something. I'd be pleased to search for and file a bug, but I want to make sure I know the extent of the bug (i.e., is the bug that the information is completely unavailable, or just that it is unavailable to ordinary users via the web-based interface).
