Comment (by simonpj):

 mmm.  So it looks as though ''promoted'' tuple data cons are not handled
 by the special encoding in `Note [Symbol table representation of names]`
 in `BinIface`.

 Adding them to `knownKeyNames` may be one solution.  But another, and a
 more consistent one, is to fix up the encoding described in that Note so
 that it does handle promoted tuple data cons.  Let's not have several
 different fixes for the same problem!
