    An application running as non-root on a bug-free kernel will never cause a 
    panic no matter what it does.
    An application running as root can cause a panic by modifying block devices 
    that are mounted, by doing an insmod type operation with something that's not 
    a valid bug-free module which matches the kernel version, or by many other 
    strange things.
    Sudo does not try to load modules, modify block devices, or do anything else 
    that has potential for danger.  So (barring catestrophic bugs in sudo or 
    minor bugs that are actively being exploited) it won't do anything that can 
    justifyably cause a panic.
    Therefore the panic indicates a bug in the kernel (or hardware failure), pure 
    and simple.
    Please try out SE Linux, then you'll know what we're talking about here.
