"Comment & close MR" doesn't comment

I wrote a comment on a MR and clicked the Comment & close merge request button.

The MR got closed, but my comment didn't get displayed. This message appeared:

Observed on GitLab Community Edition 8.6.1 a96d737b.

Milestone changed to 8.6

@anondorf I believe this was fixed in one of the 8.6 patches (cc @jschatz1 to confirm/close), but aside from that, there have been several security-related patches since then, so be sure to update your install to keep it secure!

Is fixed. Thanks @rspeicher

Status changed to closed
