WE are running 2.0.17 and have managed to create a situation and dont know
how to resolve it - or whether its a defect
Someone created 2 reviews with code changes that were dependent.
They marked Review 2 as Depends On Review 1 - this then updated the
'Blocks' field.
They then marked Review 1 as Depends On Review 2 - as they felt that both
reviews had to be committed together.
However the server then starts to give us lots of errors:
Traceback (most recent call last):

return _iterencode(o, 0)
ValueError: Circular reference detected
It maybe that the double linking is incorrect usage - however having been
able to get into that situation. If we try to remove one of the 'Blocks'
fields we just get a spinning 'Loading' icon and are unable to move past
this to remove the Circular Reference.
Not sure if you think this is user error, a defect or a combination of both
- but thought I would share it.
Cheers
