I just experienced exactly the same bug. Banshee opened in the launchpad and, as I found out, on the desktop, but it was invisible. I got the same stack trace as in the original post.
I ran the gconftool command in #11 after finding this report, restarted banshee and now it works again. It seems that something is still blocking this. I am running Oneiric. ** Changed in: banshee (Ubuntu) Status: Invalid => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/768948 Title: banshee fail to launch To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/banshee/+bug/768948/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
