[squid-users] Squid 3.1 and strange "Bad header encountered" error

Hi Squid users,

I think I need some help to understand a new error with squid. :(
I've got several squid boxes, all in 3.0 branch (reverse proxy cache).
All is ok.

Now, I've tried to upgrade one (and only one boxe) to 3.1 branch
(Starting Squid Cache version 3.1.3 for x86_64-pc-linux-gnu...).
This a debian package of squid.

Several times a day, the new squid 3.1 give me theses errors :
2010/06/07 20:14:15| WARNING: HTTP: Invalid Response: Bad header
encountered from http://mypeer_example.com/myimg.gif
<http://image.jeuxvideo.com/pics/forums/bt_forum_profil.gif> AKA
mypeer_example.com
<http://image.jeuxvideo.com/pics/forums/bt_forum_profil.gif>.myimg.gif

No errors like thos on all other 3.0 squid boxes.
No error or warning on the cache peer farm. :(

This user seems to have a similar issue.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=582270

Any idea ?

Best regards.
