Courier response that looks like:
BODYSTRUCTURE (("text" "" NIL NIL NIL "binary" 12100 NIL ("inline" NIL)
NIL)("text" "html" NIL NIL NIL "binary" 10516 281 NIL ("inline" NIL) NIL)
"alternative" ("boundary" "_----------=_113815540225145195172") NIL NIL) FLAGS

Triggers the Net::Imap parser error in match because of the surounding parenthesis around ""inline"
NIL".

A message in the same mailbox that returns:
BODYSTRUCTURE ("text" "plain" ("charset" "iso-8859-1") NIL NIL
"quoted-printable" 1515 46 NIL NIL NIL) FLAGS
does not raise the error.

It seems that the response doesn't contain body-fld-md5.
