Vacation pipeing dies with upgrade

["Daryle A. Tilroe" <daryle@amc.ab.ca>]

I have just upgraded from 2.99.48p2 under SunOS4.1.3_U1 to
2.99.50snap5 under RedHat Linux 5.0.  After a bit of fiddling I
seem to have everything working again except pipeing to 
vacation.exe does not seem to work anymore.  I get weird pipe
errors and the message either sits in the transport queue forever
or it cores and disappears after a while:

local/pipe.thomas@amc.ab.ca:
        72329-2560:     shell-init: could not get current directory:
getwd: cannot access parent directories [exit status
126] (retry in 8m1s, expires in 2d23h, tries=1)
          id   
<Pine.SUN.3.91.980530051914.16612B-100000@edson.ee.ualberta.ca>, 937
bytes, age 21s
          from  data@edson.ee.ualberta.ca
          to    "|/usr/mail/zmailer/bin/vacation.exe -a thomas ttj"

local/pipe.daryle@amc.ab.ca:
        72329-2559:     shell-init: could not get current directory:

          id   
<Pine.SUN.3.91.980530045859.16612A@edson.ee.ualberta.ca>, 908 bytes, age

          from  data@edson.ee.ualberta.ca
          to    "|/usr/amc/zmailer/bin/vacation.exe -a daryle data"

One curiosity is a router -i session differs slightly between the two
versions:

old:
z# router thomas
<root.interactive@amc-edm.amc.ab.ca>: address: thomas
(((local ttj ttj g1)) ((local pipe.ttj
'"|/usr/mail/zmailer/bin/vacation.exe -a thomas ttj"' g1)))

new:
z# router thomas
<root.interactive@apollo.amc.ab.ca>: address: thomas
(((local thomas ttj@amc.ab.ca g1)) ((local pipe.thomas
'|/usr/mail/zmailer/bin/vacation.exe -a thomas ttj' g1)))

Notice especially the different quoting around the vacation pipe.

Any ideas?
