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

Asked by Eliah Kagan on 2011-10-17

As a subscriber to https://answers.launchpad.net/ubuntu/+source/linux/+question/174557, I received a notification that said:

Question #174557 on linux in Ubuntu changed:
https://answers.launchpad.net/ubuntu/+source/linux/+question/174557

   Linked to bug: #174698
   https://bugs.launchpad.net/bugs/174698
   "Angle brackets should be converted in comments"

I know the display name of the user who did this (or, technically, what I know, I suppose, is that user's display name at the time Launchpad emailed me about the change), from this email header:

From: Andreas Kielkopf <email address hidden>

But there are two users with that display name:

https://launchpad.net/~a-kielkopf
https://launchpad.net/~andreas-kielkopf

How do I know which account it is? (I want to ask this user about why this bug was linked. But this is also a general question I've wondered about...but just not had to deal with until just recently.)

I'd be pleased to provide additional email headers upon request.

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).

This information is not stored as far as I can tell. That's an
oversight and I guess it wouldn't take much to fix, though we have no
way to recover past information.

A quick and dirty half-fix could be to include the user ID in outgoing
emails.

We're not really focusing on the Answers application at the moment,
but if you file a bug about it perhaps someone motivated from the
community could pick it up and we can help them get a fix into shape
and landed.

Gavin.

Thanks--I've filed bug 881154 for this.

Thanks Gavin Panella, that solved my question.
