This is actually the result of a bad default value. From the 
notes file of release 2.6.0 (not yet released):

Bad choice of default values for MaxHeaderSize (256) and MaxBodySize 
(1024). This in combination with a badly formatted error message makes the 
resulting behaviour hard to diagnose.

Set these directives in the config file to something appropriate (higher).
