I can explain what but not necessarily why or the consequences.
The qrunner code processing an incoming message has extracted a
Content-type: header from the message expecting it to be of the form
'maintype/subtype'.
The code is trying to separate the two parts of the mime type, i.e.
'maintype' and 'subtype', by splitting the string into two parts with '/'
as the delimiter between the parts.
This split operation is failing because the Content-type: header value
there has either no '/' character or more than one '/' character in it. In
either case the header value in the message concerned is malformed.
I haven't looked beyond the obvious to determine what is done with/to the
message having the apparently defective header.
