Ah, yeah that's certainly not right. It's due to the asset override in GJs core activity parsing class, which shouldn't be there. Comments on posts made on a GJ stream should be tied to the activity unless it's on activity of say GJ Photos (then they're tied to that photo). Have added a bug ticket and fixed for a nightly build. Quickfix is below if you don't want to wait. Note this will not retroactively fix comments incorrectly linked (there is no way to automate fixing them, sorry).
