I can verify that apt-get does have problems with chunked transfer
encoding. Of the 15 Packages.gz files that I fetched through a proxy
that uses chunked encoding 3 of them failed to be uncompressed. All
of these three, and only these three, had a CR as the first character
of the chunked data (I captured all of the data streams in each
direction).
Disabling the use of chunked encoding removes the problem.
Examination of the files that fail show that they do conform to the
requirements for chunked encoding (chunk-size is correct for
chunk-data, CRLF in correct places).
Since there is a patch available it would seem simple to apply this
and close this bug.
