[Serusers] Reg. 500 Internal Server Error

It seems to me that the 500 is not generated by SER and comes from
downstream instead. SER would add Warning and wouls not add Date header
field to replies. I don't see any obvious reason why the UAS should send
a 500 -- most likely its parser is not too robust and get confused by
some unusual syntax (whitespace in front of 'branch', symbols in branch
value, etc.)
