Even though from Rizin's post I understand people are looking at this, it would still be a good idea to make a bug report about it, so the test team can also try to find out what is causing this. Could you please go here and make a new report? The information you gave above may be very useful, so copy-paste it there please.
If you think you're causing this issue, please do it again now! I added a little bit of code to help work out what's wrong.
[I tried to submit a bug, but this account would work there. I tried to register but never got the registration email.
Yeah, I think we just finally fixed it.
