addendum, the focus of the bug report I would intend to be that you were not able to submit an error report, and _not_that 'game-id' was null. Those are two different problems.
The game-id problem is worth an error report. Though, it requires some investigation into the logs and is rooted somewhere in 2.5. I don't think I have bandwidth to do that, hence I would not bother cutting a ticket for the game-id being null problem beyond what you've reported here already.
