Description Jasper Lievisse Adriaanse 2011-05-18 12:30:26 UTC 
Hi,

Upon launching gnome-panel I get the following output in my console:
cerebrum:jasper {115} gnome-panel

cerebrum:jasper {153} 

Amongst others I have installed: glib 2.28.6, gtk+ 3.0.9, gnome-panel 3.0.0.1, gnome-desktop 3.0.1. Any idea what's going on or how to further debug this?
Comment 1 Vincent Untz 2011-05-23 22:09:14 UTC 
I pushed a fix. Btw, it seems you're running without gnome-session according to the errors. There's no guarantee the panel will work 100% reliably (some features like logout will not work, I guess).
Comment 2 Jasper Lievisse Adriaanse 2011-05-23 22:12:22 UTC 
Thanks. I was running it indeed without gnome-session as I was merely testing the panel in openbox.
