I have had a go at solving this.  I have been able to reproduce the 
problem once.  It appears that ppop has the wrong permissions.  It 
should be:

-rws--s--x 1 ppr ppr 131712 2006-08-31 15:21 /usr/lib/ppr/bin/ppop

I am still trying to figure out why it sometimes gets installed with the 
wrong permissions.
