I am getting this problem reliably, though not always with the same applets.

The panel does not appear while waiting, and the offending applet/s (in this case, the timer applet) is/are not present when it finally does. Any suggestions on how to collect more useful information on this? ** Changed in: gnome-panel (Ubuntu) Status: Expired => New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-panel in Ubuntu. https://bugs.launchpad.net/bugs/640240 Title: panel-applet-frame.c:1310: failed to get Bonobo/Control interface on applet OAFIID:GNOME_NotificationAreaApplet: Unknown CORBA exception id: 'IDL:omg.org/CORBA/COMM_FAILURE:1.0' -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
