memory.

Simon,

Could you post the IOS and platform you are using, so we can try to
reproduce it?

Trying to make a model:

R1-----------bridgesw1-----bridger6
R5-----------bridgesw1-------|

There is no loop here, so I can not see STP having a role on this problem.
No matter where the Root is, all ports will be forwarding. But a bug would
not surprise.

Do you have a Sniffer to check where packets stop?
