Comment (by seliopou):
The problem is that the {{{GlobalRdrElt}}} for {{{B.ByteString}}} has two
{{{ImportSpec}}}s for its {{{Provenance}}}, only the first of which (the
"wrong" one, i.e., {{{Data.ByteString.UTF8}}}) is being added to
{{{minimal_imports1}}}, which is then used to construct
{{{unused_imp_mods}}} in {{{reportUnusedNames}}}
(rename/RnNames.lhs:1084).
