[squid-users] Squid3 / ICAP question

I'm using Squid 3.0.STABLE19-1 with c-icap - replacing an existing
"sandwich" setup of squid2-dansguardian-squid2.

To my great amazement, things seem to work flawlessly.

But... when I'm restarting c-icap, squid reports:

--- snip ---
The following error was encountered while trying to retrieve the URL: http://www.google.de/ig?hl=de
ICAP protocol error.
The system returned: [No Error]
This means that some aspect of the ICAP communication failed.
Some possible problems are:
The ICAP server is not reachable.
An Illegal response was received from the ICAP server.
--- snip ---

And that's although c-icap is already running again.
Issuing an "squid3 -k reconfigure" solves the problem.

But why? How can I prevent the need to do that?
