Hi Hans (apologies for not hitting the right button to reply to the 
mailing list just before),
I checked with context version 2012.07.07 15:04, and it is still broken. 
I have pasted a minimal example below.
Another thing I noticed was that 'align' feature of \setupformulas is 
broken too. (It has been commented out below in case you want to test 
that too.
Best regards,
Prash
