Empty /error log lines (a lot of them)

Hi,

I am using NGINX 0.8.54 on Ubuntu 11.04, and I am getting a lot of
weird log entries in nginx access file. The structure is somewhat like
below, but as  you can see there is no method, URL, referer, user
agent, etc. And, I see bunch of entries for different IP addresses (3
to 30-40 entries per IP)

It might be a browser issue, but since I am seeing a lot of these, I
just wanted to ask here if anyone has seen this before.

Thanks...
