This is still a problem on Karmic. Here is an updated reproducer for
Karmic. Create monitor_private_dir.sh:

#!/bin/sh
set -e
private="$HOME/.Private"
while true; do
	if ! mount | grep -q "$private"; then
		echo "$private was unmounted." | ts
		ecryptfs-mount-private
	fi
	sleep 1
done

Then add to the user's crontab:
*/1 * * * * /bin/ls >/dev/null
*/1 * * * * /bin/ls >/dev/null
*/1 * * * * /bin/ls >/dev/null
*/1 * * * * /bin/ls >/dev/null
*/1 * * * * /bin/ls >/dev/null
*/1 * * * * /bin/ls >/dev/null

*/2 * * * * /bin/ls >/dev/null
*/2 * * * * /bin/ls >/dev/null
*/2 * * * * /bin/ls >/dev/null
*/2 * * * * /bin/ls >/dev/null

Then run the monitor:
$ ./bin/monitor_private_dir.sh
Jul 17 07:08:11 /home/jamie/.Private was unmounted.
Jul 17 07:09:07 /home/jamie/.Private was unmounted.

It might take a couple minutes to trigger, but it does trigger fairly
easily. I bet increasing the number of concurrent cron jobs will make it
hit even faster. This was also done with an encrypted private directory,
not encrypted private $HOME, but would theoretically work there too.

Bug description:
Binary package hint: ecryptfs-utils

This seems to be bug #259293, but I am filing a new one as I haven't seen this in some time. Twice in the last week my ~/Private directory unmounted. Both times /tmp/ecryptfs-<user>-Private was '0'. Both times, the symlink in the unmounted ~/Private was not present.  I have a cron job that runs every 10 minutes that I can see in syslog:

Apr  9 11:15:04 hostname CRON[22771]: Mount of private directory return code [0]

It could be that bug #259293 is simply 'mostly' fixed and I coincidentally hit this twice in the last week, or it could be a new bug (I don't know).
