Bug in Requirements report

[Nigel Titley <..hidden..>]

Checking any of the "month" checkboxes in the requirements report gives 
an Internal server error

The error.log entry is

[Wed May 23 09:30:23 2012] [error] [client 91.197.17.140] Premature end

To my knowledge this bug was also present in 1.2, but I never got around 
to reporting it
