Is it a custom ICAP server?

This message means that the squid tried to send an options request to
the ICAP server and the ICAP server answer was not correct (or just did
not like to the squid)
I am suggesting to enable debug for ICAP client in squid3:
  debug_options 93,9 0,9
And search in debug messages to see what they say about. You can also
post the debug messages here.

Also grabbing the conversation between squid and ICAP server using
wireshark or similar tool will be helpful...
