[linux-cifs-client] umount fails on logout with pam_mount-0.9.14

[Clary Harridge]

I am using mount.cifs on a client running fedora core 1 and kernel 
2.4.26-rc2

Our server is running samba-3.0.2a with UNIX extensions enabled
The clients pam_mount.conf contains

smbmount /bin/mount -t cifs //%(SERVER)/%(VOLUME) %(MNTPT) -o 
"user=%(USER)%(before=\",\" OPTIONS)"
umount   /bin/umount %(MNTPT)
volume * smb scrub &     ~         uid=&,gid=% - -

The cifs mount is fine on login:
pam_mount: pam_mount: command: mount -t cifs //scrub/clary 
/students/01/clary -o username=clary,uid=clary,gid=%

but the umount has garbage info:
pam_mount: command: wnam_root_9 \360d ^H
pam_mount: error running \270\221 ^H\360\222 ^H^P\355#@\220L^I^H^X: No 
such file or directory
pam_mount: lsof output (should be empty)...
pam_mount: waiting for mount
pam_mount: error waiting for child
pam_mount: command: ^P\355#@ ` ^Hrnam^Y
pam_mount: error running p\316^I^H@\234 ^H^P\355#@\270\ ^H^X: No such 
file or directory
pam_mount: unmount of clary failed

The above happens if I use kde or gnome to login / logout
If I do a
     su - clary
then logout
     the umount is fine

WHere would the umount command be finding its path that is getting 
corrupted?
Thanks!
