patch to fix session refcounting (3.91 KB, patch) 2008-09-17 14:23 UTC, Dan Winship	rejected	Details \| Review

Description Caroline Ford 2008-05-16 16:42:22 UTC

Steps to reproduce:
1. Open applications -> accessories -> passwords and encryption keys
2. Select your primary key, right click on it and select Sync and Publish keys
3. Click on the sync button and wait
4. If it cannot get a response from the keyserver you get an error dialog box. This is very hard to close. I then got the sigsegv.

https://bugs.edge.launchpad.net/ubuntu/+source/seahorse/+bug/198562 is the Ubuntu bug, with 5 duplicates. The stacktrace is from 2.21.92, I have confirmed with 2.22.1.

Other information:
https://bugs.edge.launchpad.net/ubuntu/+source/seahorse/+bug/198562 is the Ubuntu bug, with 5 duplicates. The stacktrace is from 2.21.92, I have confirmed with 2.22.1.

Comment 1 Stef Walter 2008-09-13 15:55:56 UTC

I cannot duplicate this problem, but this looks like a libsoup bug that seahorse is aggravating.

Comment 2 Dan Winship 2008-09-16 17:00:23 UTC

(In reply to comment #1)
> I cannot duplicate this problem

It happens when you try to sync to a keyserver that isn't responding. (eg, adding hkp://localhost:9999/ as a keyserver and trying to sync to it will trigger the bug). Ubuntu adds keyserver.ubuntu.com into the seahorse defaults, and apparently that server must go down a lot, cause people to trip over this bug.

> but this looks like a libsoup bug that seahorse is aggravating. 

Yup. (Caused by unreffing the session from the queue_message callback, which is *supposed* to work, but apparently doesn't in this particular case.)

Created attachment 118879 [details] [review]
patch to fix session refcounting

This should fix the bug. We're in hard code freeze now, but this will be committed post-freeze for GNOME 2.24.1.

Comment 4 Dan Winship 2008-09-30 15:43:59 UTC

Fixed on trunk (differently from the earlier patch) and will eventually make it into libsoup 2.24.1.

Comment 5 André Klapper 2008-10-22 15:47:34 UTC

Has this gone in for 2.24.1?
