Thanks for the report. I'm not 100% certain why it happens in 5.04.2,
but it doesn't happen in the HEAD. The error message is still not
great, but at least it's not gibberish.

Data.hs:288:
Could not deduce (ReprType r t) from the context ()
arising from use of `getter'' at Data.hs:288
Probable fix:
Add (ReprType r t) to the expected type of an expression
In the first argument of `runDR', namely `(getter' repr)'
When checking the type signature of the expression:
runDR (getter' repr) "..." 0 rContents :: forall t. CC t
In a 'do' expression:
val <- runDR (getter' repr) "..." 0 rContents :: forall t. CC t
