Description Chase Venters 2008-06-24 23:28:11 UTC

Version:            (using KDE 3.5.9)
Installed from:    Gentoo Packages
Compiler:          gcc (GCC) 4.2.2 (Gentoo 4.2.2 p1.0)
 
OS:                Linux

Konqueror 3.5.9 fails to download correct "NZB" files from the website http://binsearch.info/. No error messages are shown or generated, and Konqueror creates a disk file in the location expected and with the name expected. However, the file created is nothing more than a short amount of gibberish and looks nothing like the expected well-formed XML.

Mozilla Firefox 2.0.0.13 was tested to download these same files correctly. Other browsers and other Firefox versions seem to download the NZB files correctly as well.

I ran a search for "CentOS" with "Maximum age of post" set to "-- show all --" and created an NZB for "Posting barebones VMware image: CentOS 5.1 i386 [00/37] - "CentOS 5.1 i386 noX.rar.nzb" yEnc (1/1)" in both browsers. I will attach the NZB file as created by each browser.

I also made a libpcap capture for each browser to examine the HTTP session. In each case, the server (lighttpd/1.4.19) appears to send identical gzip-encoded data, regardless of which browser makes the request.

This is the corrupt data that Konqueror 3.5.9 saved to disk.

Packet capture for Konqueror requesting CentOS NZB

It appears from a stare-and-compare that lighttpd serves exactly the same
compressed data to both browsers.

Seems to be working ok in trunk.

Comment 6 Chase Venters 2008-06-25 19:45:45 UTC

When you say that it is working okay in trunk, do you mean that it is working fine under KDE 4+? Are fixes still going into the 3.5 branch or has that work ceased?

Works in KDE 4.x and 3.5.x is now legacy...
