 Thanks for the information.  Please do send along any further information
 if you find it.  I use qmail on the sourceware.cygnus.com site so I'm
 afraid I can't provide much help with this one.
 
 I suppose we should put together some kind of FAQs for GNATS; this
 would definitely be high on the list if it is a problem people will have
 with default sendmail installations.

 Ok, I found the secure solution for RedHat, may work on all sendmail
 installation using smrsh:
 smrsh strips the path from an executable with s-Bit set and tries to
 find it in a special directory, according to O'Reilly's Sendmail Bible
 (Costales & Allman) this is /usr/adm/sm.bin. However, on my RedHat,
 it is /etc/smrsh/.
 
 The secure solution is to create a link in this dir:
     ln -s /etc/smrsh/queue-pr /usr/local/libexec/gnats/queue-pr

 I found another fix related to the 
 "queue-pr not available for sendmail programs"-Problem:
 
 The offending Program is smrsh: It is used in modern sendmail distributions
 for secure executing of "| blah" aliases.
 It seems, that queue-pr is not considered as secure (because of the
 s-bit maybe) and smrsh refuses to execute it.
 
 Fix: find the line "Mprog, ...." in /etc/sendmail.cf and replace
 /usr/sbin/smrsh with /bin/sh. Be aware: this seems to be a security hazard.
 I'll read on: Maybe, there is a way to convince smrsh, that queue-pr is secure.

 Hi!
 I pinned id down: queue-pr -q does an Segmentation Fault, iff 
 gnats-db/gnats-adm/states exists:
 A strace of queue-pr -q showed:
 -----------------------------------------------------------------------
 ...
 ...
 open("/usr/local/share/gnats/gnats-db/gnats-adm/states", O_RDONLY) = 3
 fstat(3, {st_mode=S_ISGID|S_ISVTX|0632, st_size=0, ...}) = 0
 mmap(0, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x400140
 00
 read(3, "#\t\t    Possible states for a P"..., 4096) = 2352
 --- SIGSEGV (Segmentation Fault) ---
 +++ killed by SIGSEGV +++
 -----------------------------------------------------------------------
 and removal of the offending file fixed the problem.
