Happens to me as well, but it doesn't restart chrome. The whole screen goes black and I have to force shutdown the Chromebook.

could be the same issue as  crbug.com/602918 . lgcheng@, what do you think?

 crbug.com/602918  is shelf launcher context menu related only and affects all apps which have shelf shortcuts.

According to the description, I don't think this bug is related to  crbug.com/602918 .

That's exactly the case. This happens when you open the 2nd tab/window using menu on the launcher item. "New Window", "New Tab".

Sorry for my misunderstanding. If that is the case can you check:
This also happens to other apps through shelf shortcuts?

If so, should be fixed with the merge this noon.

https://bugs.chromium.org/p/chromium/issues/detail?id=602918#c19

Let me know if it is not fixed after the merge.

And FYI, error log should be like:

Which is not what I see from the error log in #1

Yeah, it seems to be the same issue. The Netflix extension will produce the same system crash when I click `New tab`.

On the Chrome Remote Desktop extension, I can click `New window...` without issue, so it's not every context menu.

Yes, it not every context menu. It is only shelf context menu. And it can be caused by clicking any context menu item from shelf context menu.
I mark it as duplicate of 602918 now. Let me know if it is not solved after merge.

Well, I'm not on dev or canary branches, I'm on beta branch. I'm not sure how soon beta gets updated.

I am not sure but it seems it is updated everyday.

I've got 52.0.2717.5 today and could no longer reproduce this. FYI.
