Your error message mentions ICAP and Sophos, which appears to be
a virus-scanning transparent proxy server.
I can download and unpack rdoc-3.8 on my machine, so it must be
a bug of your proxy server when encountering test/binary.dat (a
truncated tar.gz file) inside the rdoc test directory for rdoc 3.8.
You should report this issue to your network administrators and/or
sophos who sold you the proxy server.
