Description

[Patrick Brosset <:pbro>]

STR:
- open the console panel on this page
- enter `console.group()` and submit
- something expected happens
- now look at the browser console and notice that there is an error: "TypeError: body is undefined"

Also:
- open scratchpad
- enter `console.group()` and execute the code
- the browser console also contains the same error.

The error comes from webconsole.js:2397:9 which is:

Apparently, in some cases message.groupName here:
http://searchfox.org/mozilla-central/rev/dbbbafc979a8362a1c8e3e99dbea188fc832b1c5/devtools/client/webconsole/webconsole.js#1332
is undefined.

FYI , there won't be similar issue in the new console frontend since a default label is added in Bug 1307873. Should we use this default label in the webconsole.js file anyway ? Or can we just let this as is, since we will be switching to the new frontend in a not so distant future ?

IMO if this is resolved in the new frontend we can leave this one open for verification but no need to update the old UI

Can't reproduce, seems to be an old console frontend bug only.
