The subject line of the commit is ok (although it could ideally be shorter).

On Thu, 26 Jul 2012, Samuel Pitoiset wrote:

When the server sends a chunk size packet less than 4 bytes long
we return a proper error code.

Returning a proper error code is already in place, this commit doesn't change that at all. In this case, this second paragraph of the commit message can be dropped altogether.

I'd rather have the error message say "Too short chunk size change packet (%d)". Also note, originally this said "chunk size _change_", but you change it to "chunk size _report_".
