Description

Diegoe found this while using Epiphany/WebKit. The problem happens with the following site:

https://webaloe.ulima.edu.pe/portalUL/

Here's the relevant WebKit bug: https://bugs.webkit.org/show_bug.cgi?id=24954

The problem seems to happen because the server gives us a 302, and sends back a Connection: close, but sends a fair amount of \r\n's as a body, which confuses libsoup. I'm going to attach a small test case reproducing the problem.

Version: 2.25.x
