Hi, I can confirm this bug. However, it's not always reproducible as the origin of the problem seems to be a race condition which causes gnome- panel not to show up. I also experienced the problem in a virtual machine (kvm host on Debian Squeeze) and that's I also had to use the non-accelerated 2D desktop.
When installing the current beta of Ubuntu Natty 11.04, the panel would load fine. However, after installing the updates as of Thursday, the problem showed up. After installing the updates, rebooting Ubuntu and logging in, the panel would be gone. The panel can be brought back by invoking the "Run command" dialog, typing "xterm" or "gnome-terminal" to start a terminal and then killing the panel with killall -9 gnome-panel and then restarting the panel with gnome-panel & Since the last software update today, however, the problem seems to be gone. I have rebooted my virtual machine with Natty several times but the panel shows up all the time now. So, the bug might be fixed already. If you want to reproduce the bug, I suggest installing the Ubuntu Natty beta in a kvm virtual machine, together with all updates available. There are also other problems with the default skin when using the beta in a kvm machine: the skin falls back to the ugly GNOME standard theme without any skins.
