How tight on memory are you running the system? The BUG is probably 
happening because the guest is failing to allocate a page of memory 
below 4GB. Since Xen tries to give out memory below 4GB last, that 
probably means there is very little available memory.
Obviously we need a better fallback strategy than BUG(). :-)
