Crash when navigating HTTPS uri through proxy

I think this is a bug in libsoup2.4-1 2.36.0-0ubuntu1. It may be fixed in libsoup 2.36.1, see https://bugzilla.gnome.org/show_bug.cgi?id=661758

Hey Jiri,

I downloaded libsoup 2.36.1 from SoftPedia, but I don't have a clue how to build / install it.

I did something else which seems to work:
- I installed webkitgtk 3.0 oowtk from the webkit-team ppa;
- I installed midori_0.4.2-1~oowkt1_i386.deb (downloaded from the launchpad website).

Although I installed a different webkitgtk version, the version of libsoup is unchanged (!).
I tested with the HTTPS websites of Duck Duck Go, Hotmail, and Facebook.

Cheers,
Pesmontis

libsoup is not a part of webkitgtk, it's a separate library

It's good that I wrote 'seems' to work, because it doesn't.
In midori_0.4.2-1~oowkt1 I didn't set a proper proxy port number
(left it at 8080, while the proxy addres was set as 192.168.0.1:8118)..

Alright, with libsoup 2.36.1 it works.
I used this page to build & install libsoup:
http://www.linuxfromscratch.org/blfs/view/svn/basicnet/libsoup.html

I have a similar problem with 2.36.0-0ubuntu1, which also happens with the vanilla upstream 2.36.0 (built from source), though my crash is in soup_socket_is_ssl. I can't repro my crash using 2.36.1 built from source on Oneiric, or with 2.36.1-1ubuntu1 on Precise (as of 2011-01-12).

My crash happens when Eclipse hosts WebKit GTK, after being redirected to an SSL web site with HTTP and HTTPS proxies enabled the entire time. Takes down the entire JVM (see the attached JVM crash report). I'm associating my problem with this thread because there were just a few upstream changes between 2.36.0 and 2.36.1, and I think we're just seeing different symptoms of the same problem.

2.36.1 seems to fix this issue completely for me, and it would be nice to see an update to Oneiric.

There are only 3 fixes between 2.36.0 and 2.36.1, not sure which one fixes it since the bugs referenced to the one fix look different from this one...

oneiric has seen the end of its life and is no longer receiving any updates. Marking the oneiric task for this ticket as "Won't Fix".
