[squid-users] Strange entries in cache.log (3.0.STABLE10)

Hello,
I am seeing entries like below quite frequently. It looks to me as if the
Content-Language and Content-Location headers are not parsed correctly, since I
cannot see this stuff in the traffic going to the squid. In this config Squid
has a WebWasher installation as parent and has an imagefilter as
ICAP-respmod.
