Problem with XML Dissector

[Alexandre Vieira <nullpt () gmail com>]

Hi list,

I'm having trouble dissecting an HTTP POST that comes with "Content-encoded
entity body (gzip)" from the client side.

I'm using TShark 1.0.13
Compiled with GLib 2.4.1, with libpcap 1.1.1, with libz 1.2.3, without POSIX
capabilities, with libpcre 8.2, without SMI, with ADNS, without Lua, without
GnuTLS, without Gcrypt, without Kerberos.

Running on SunOS 5.10, with libpcap version 1.1.1.

Built using gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath).

All requests that are submited without gzip compression are dissected
correctly.

I'm using tshark like:

$ /usr/local/bin/tshark -o tcp.check_checksum:false -r  /tmp/mycap_test.cap
-V -d tcp.port==10010,http

The requests that are dissected correctly:

Hypertext Transfer Protocol
    POST /App HTTP/1.1\r\n
        Request Method: POST
        Request URI: /App
        Request Version: HTTP/1.1
    Content-Type: text/xml\r\n
    User-Agent: CLIENT1/3.0/1.0\r\n
    Authorization: Basic XXXXXXXXXXXXXXXXXXXX\r\n
        Credentials: xxxxxx:xxxxxx
    Content-Length: 561\r\n
        [Content length: 561]
    Cache-Control: no-cache\r\n
    Pragma: no-cache\r\n
    Host: 192.168.87.8:10010\r\n
    Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2\r\n
    Connection: keep-alive\r\n
    \r\n
eXtensible Markup Language
    <?xml
        version="1.0"
        encoding="UTF-8"
        ?>
(....................................................)

The requests that don't work:

Hypertext Transfer Protocol
    POST /App HTTP/1.1\r\n
        Request Method: POST
        Request URI: /App
        Request Version: HTTP/1.1
    Content-Type: text/xml\r\n
    User-Agent: CLIENT2/3.0/1.0\r\n
    Authorization: Basic XXXXXXXXXXXXXXXXXXXX\r\n
        Credentials: xxxxxx:xxxxxx
    Content-Encoding: gzip\r\n
    Accept-Encoding: gzip\r\n
    Content-Length: 566\r\n
        [Content length: 566]
    Cache-Control: no-cache\r\n
    Pragma: no-cache\r\n
    Host: 192.168.87.8:10010\r\n
    Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2\r\n
    Connection: keep-alive\r\n
    \r\n
    Content-encoded entity body (gzip): 566 bytes
        Data (566 bytes)

Anyone can shed a light on this?

Thanks in advance!
