This is exactly the problem I was seeing all last week. I re-imaged my 
base system to clean up the filesystem, and that appears to have solved 
the problem on two different machines. So it seems that the bug is also 
exposed or affected by something in the filesystem, possibly an out of 
date library, or something. The only clue I can offer (which may just be 
coincidence) is that all the affected systems had previously run xen 2.0 
in the past, while the new (working) system was a clone of a system that 
had only ever had xen 3.0 on it.
