Hello :-)
The issue seems to be with vchanger 0.8.5 and auto-mounting; it may be
specific to Slackware 13.0.
After disabling auto-mounting, manually mounting the USB HDD and
reconfiguring Bacula sd to suit, the "label barcodes" command worked.

Subject: "update slots scan" gets "ERR=Unknown error during program execvp"
Hello :-)
This cross-posted from the vchanger mailing list because the problem cause
may be in either bacula-sd or vchanger -- or both, or neither if it's my
error as is most likley :-)
I'm setting up bacula 5.0.1 with vchanger 0.85 following the (very good,
thanks) procedure in vchangerHowto.html from the tarball.
All was going well until issuing the bconsole "label barcodes" command
(details below). Investigating using the bconsole "update slots scan"
command with the bacula-sd running with debug in the foreground gave:
[CODE]
28-Feb-2010 20:54:23 ps1-sd: autochanger.c:196-0 Run
program=/usr/bin/vchanger /etc/bacula/changer1.conf load 1
/var/bacula/changer1/0/drive0 0
28-Feb-2010 20:54:23 ps1-sd: autochanger.c:207-0 load slot 1, drive 0, bad
stats=Unknown error during program execvp.
28-Feb-2010 20:54:23 ps1-sd: autochanger.c:214-0 load slot 1
status=268435711
[/CODE]
Stopping Bacula and simulating the apparent problem command, it ran OK:
[CODE]
root@ps1:~# /usr/bin/vchanger -u bacula -g bacula /etc/bacula/changer1.conf
load 1 /var/bacula/changer1/0/drive0 0
root@ps1:~# echo $?
0
[/CODE]
That's the essence of the problem. What follows is more detail in case it
helps.
I tried re-initialising vchanger's on-disk data by:
{CODE]
root@ps1:~# vchanger -u bacula -g bacula /etc/bacula/changer1.conf initmag 1
<== to automount
magazine in bay 1 (/mnt/vchanger/efa8a079-ab80-41c9-b018-85810dd3c45d)
already initialized as magazine 1
root@ps1:~# cd /mnt/vchanger/efa8a079-ab80-41c9-b018-85810dd3c45d/
-rw-r----- 1 bacula bacula 1 2010-02-28 20:39 loaded0
root@ps1:/mnt/vchanger/efa8a079-ab80-41c9-b018-85810dd3c45d# rm *
root@ps1:/var/bacula# mv changer1/ changer1.aside
root@ps1:/var/bacula# vchanger -u bacula -g bacula /etc/bacula/changer1.conf
initmag 1
created magazine 1 in bay 1
[/mnt/vchanger/efa8a079-ab80-41c9-b018-85810dd3c45d]
[/CODE]
Tested again but got same results.
Here's more detail of the testing, starting with the bconsole "label
barcodes" command which got:
[CODE]

[/CODE]
The bconsole "update slots scan" command got:

As far as I can tell, vchanger is working OK; perhaps the problem is in
bacula-sd.
Any ideas?
