FUSE mount from udev gives "Transport endpoint is not connected", fine as root

I have a udev rule that mounts my encfs encrypted backup disk:

`
ACTION=="add",KERNEL=="sd*1",ENV{ID_SERIAL}=="Seagate_GoFlex_Desk_NA0MEYKM-0:0"
,SYMLINK="ext_hd",RUN+="/root/bin/mount.encfs 'Large Backup Drive' /dev/%k"

` The contents of mount.encfs are: #!/bin/bash set -e export XAUTHORITY=/home/me/.Xauthority export DISPLAY=:0.0 NAME=$1 DEV=$2 ENCRYPTED_MOUNT_POINT=/media/ext_hd.encfs UNENCRYPTED_MOUNT_POINT=/media/ext_hd [ ! -e $ENCRYPTED_MOUNT_POINT ] && mkdir $ENCRYPTED_MOUNT_POINT [ ! -e $UNENCRYPTED_MOUNT_POINT ] && mkdir $UNENCRYPTED_MOUNT_POINT mount -t ext4 $DEV $ENCRYPTED_MOUNT_POINT encfs -o allow_other --extpass="ssh-askpass $NAME" \ $ENCRYPTED_MOUNT_POINT $UNENCRYPTED_MOUNT_POINT When I insert the disk, I get the prompt, but when I try to ls /media/ext_hd, I get the classic FUSE: ls: cannot access '/media/ext_hd': Transport endpoint is not connected If I manually umount then manually run my mount.encfs, it works. The output from mount is the same for the two cases: encfs on /media/ext_hd type fuse.encfs (rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other) I'm at a loss as to what could cause this, whose fault it is, or even what the next debug step should be. Any ideas?
