The error we get looks like

<class 'psycopg.ProgrammingError'>: ERROR: value "20030921115726" is out
of range for type integer select count(*) from _file where
id='20030921115726' 

This happens when I view a message (or an issue containing a message)
with a certain string in it.  I can reliably make the web interface
explode by pasting that string into a new message (which I will attempt
next here)
