Description of problem:

after updating a bug, above the page header bz prints "No recipient addresses found in header" and continues to print the page as normal.  This happened twice, once with bz 447769 and 459721.  The page appears to be normal and includes that it thinks it sent mail to a series of people.  I believe the fields all updated correctly, simply that it printed this message, which looks a bit like perhaps it didn't send the mail?


How reproducible:

Happened the last two times I've updated bugs.


Steps to Reproduce:
1. opened my hts bugs list (saved query)
2. opened in a new tab the bugs above
3. add a comment, on one bz added a needinfo status
4. select commit
  
Actual results:
Page prints normal except that it starts with the above message.

Expected results:
There would be no message above the header.
