Steps to reproduce:
The problems was produced when receiving an email where the last header in the message was "From:" and it was empty. see below for the header dump


Actual results:
The message is displayed with no headers at all

Expected results:
The message should be displayed with all the standard header information that can be found in the message

Does this happen every time?
yes

Other information:
