Re: [Pan-users] OK, suddenly Pan 0.13.2.90 segfaults

[John Morris]

Does your Pan executable have one of the setuid bits set on it? That sounds 
like what it is complaining about.  As root, try "chmod a-s 
/usr/local/bin/pan"  (or wherever you pan executable lives).
This may be a side effect of strace, tough if it is suid itself.
