This problem just recently started happening on my system although I haven't made any configuration changes aside from updating packages. I think there might have been a fix released at one time, but it looks to me that recent updates have reintroduced the problem. I have this issue even running "Classic Ubuntu (No Effects)" (i.e. metacity with no composting) which used to be very stable.
