Comment 149 for bug 553745

I received this error on Oneiric 11.10 beta 1 after rebooting. I logged in, and received a message saying that there was a system problem, but with no error message. I selected to report it, and a few seconds later the plymouthd crash error came up which I selected to report as well. I had upgraded from 11.04 to 11.10 beta 1.
