Fixed.

I updated my gossip to version 0.15 and I can not see any avatar in the notifications! I have libnotify 0.4.2 and notification-daemon 0.3.5 installed.

Since I'm on edgy (libnotify 0.4.2) I don't get any image for notify bubbles. Not only for gossip, but other programs too. I think that's a problem on libnotify. I think that's the problem you have.

Applications like NetworkManager, Gnome Sensors Applet or Quodlibet displaying images in their notifications and they working correct with libnotify 0.4.2 on my machine.

I just ran libnotiy unit tests (test-image.c) and it shows only images from URI, not from pixbuf and stock. Gossip uses pixbuf most times. I think that's a libnotify bug, the problem doesn't comes from gossip as far as I know.

I tried with dbus 0.60 and images works. That's a dbus bug. By reading libnotify's Changelog I'v seen there were a bug in <0.60 which prevent from sending GValueArray and I guess this bug is back on 0.62 (ubuntu edgy's version).

I use Gentoo Linux and there is a updated version of the notification-daemon (0.3.5-r2) with a patch called 'icon-data.patch' that fixed it for me. Now I can see the avatars when the status is changed or an message arrived. All with dbus 0.62! Thanks for help!

Thanks, I reported the bug to ubuntu:
