Go to: https://developer.mozilla.org/en-US/search?q=transform&topic=svg And you get: You didn't provide a search term. Try a new search! The search term is 'transform', so this is not the correct error message.

What should be the correct error message in this case?

No idea, I don't even know why there is an error. Should have worked.

SVG isn't a valid topic for said search, so I'm going to mark this as invalid. We shouldn't allow just any topic to be appended to the URL.

This bug is about the message not being clear. It is not clear as we needed several hours to know why they was an error in this request I have opened another bug about SVG not being a topic, which is another bug.

This is not a blocker. The error message happens in very unusual case. It is more making it clear to the user.

This isn't relevant anymore, see https://www.dropbox.com/s/0sfixhkmt9t56wt/Screenshot%202013-11-11%2021.53.21.png for a screenshot of the state of ticket 915760.
