Thanks for the bug report. This is not really a bug in notification- daemon, it is just warning us that the "icon_data" hint is deprecated, which it is. It is difficult to tell exactly which app is misbehaving from the information given, however I have been able to reproduce the bug with a simple libnotify test (which I am attaching), so I am moving it to libnotify.
The problem seems to be that libnotify correctly checks the server version to see if it should use the "image-data", "image_data" or "icon_data" hint, however, unless you explicitly ask for the server information, it will choose the wrong one (or there may be a race where the notification gets sent before the server information arrives, I would need to investigate further). In the attached test code, if compiled with: gcc -o notify-test notify-test.c $(pkg-config --cflags --libs libnotify); without removing the comments around the section that fetches the server information, it will show the notification with the firefox pixbuf, but it will give the above warning in ~/.xsession-errors. However if the comments are removed, it will fetch the server version, and use the correct "image-data" hint. If we want to fix these sort of bugs in quantal, a good way to watch for notifications to track down misbehaving apps is: dbus-monitor --session --monitor "type='method_call',interface='org.freedesktop.Notifications',member='Notify'" > monitor.log; I did notice while tracking down this bug that at least python-notify2 also seems to use the deprecated "icon_data" hint. ** Attachment added: "notify-test.c" https://bugs.launchpad.net/ubuntu/+source/libnotify/+bug/1023286/+attachment/3220109/+files/notify-test.c -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1023286 Title: "icon_data" hint is deprecated, please use "image_data" instead To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libnotify/+bug/1023286/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
