The version of squid3 you are using is about 10 months old, please
upgrade to a newer version:
  http://www.squid-cache.org/Versions/v3/3.0/

Your workaround possibly is the correct.
Depending on configuration of c-icap, files bigger than a defined size
are not downloaded as normal, but instead c-icap sends to the web client
 a web page with info about download progress and when the download
completes, you are getting a link from which you can download the file.
In this case auto-upgrades will not work.

About c-icap configuration please ask to the c-icap mailing list.

Again upgrade your squid3 proxy to a newer version.
Always you can to send urls which are not working.
Also wireshark is a good tool :-)
