 From what I can tell, I'm having exactly the same problem.  I am also 
running 3.0.2.  As a test, I tried logging calls to the mount and 
unmount commands with wrapper scripts like so:

Device {
  Name = BackupDrive
  Media Type = File
  Archive Device = /mnt/backup/volumes
  Mount Point = /mnt/backup
  Mount Command = "/etc/bacula/mount-wrapper %m"
  Unmount Command = "/etc/bacula/umount-wrapper %m"
  Requires Mount = yes
  LabelMedia = yes
  Random Access = Yes
  AutomaticMount = yes
  RemovableMedia = yes
  AlwaysOpen = no
  Offline On Unmount = Yes      # Also tried "no"

}

The wrappers are pretty much what you would expect:

# cat /etc/bacula/umount-wrapper
#!/bin/sh
echo umount-wrapper called as $0 $1 $2 $3 $4 $5 $6 $7 $8 $9 >> 
/tmp/mount.log
/bin/umount $1 $2 $3 $4 $5 $6 $7 $8 $9 >> /tmp/mount.log 2>&1

+++++++

# cat /etc/bacula/mount-wrapper
#!/bin/sh
echo mount-wrapper called as $0 $1 $2 $3 $4 $5 $6 $7 $8 $9 >> /tmp/mount.log
/bin/mount $1 $2 $3 $4 $5 $6 $7 $8 $9 >> /tmp/mount.log 2>&1

+++++++

After running a couple of backup jobs, I looked at the mount log:

# cat /tmp/mount.log
mount-wrapper called as /etc/bacula/mount-wrapper /mnt/backup
mount-wrapper called as /etc/bacula/mount-wrapper /mnt/backup

It appears bacula calls the mount command as expected, but it never 
calls the unmount command.  Not only does it not do it automatically 
after a backup job completes, it doesn't even do it on an explicit 
"umount" issued from the console.

Like you, I looked at bug 830 ( http://bugs.bacula.org/view.php?id=830 ) 
which was closed as "fixed" on 2007-07-16 with the comment::  "Fixed in 
current SVN. You must have the appropriate Mount/Unmount commands 
defined in the Device resource and you must declare the device as 
removable otherwise Bacula will not try to mount/unmount it."

Am I missing something?  Is there some reason bug 830 should NOT be 
reopened?

Thx,

- Cedric
