[Click] oops on click-uninstall

[Eddie Kohler]

Hi Beyers,

Are you still getting this error?  I have not seen anything like it, at 
least on my laptop, and others haven't seen problems either.  I wonder 
if there could possibly be something like using an older proclikefs with 
a newer kernel module.  Almost certainly not but....
