virtual-tape directory error

Hello,

I run 2 copies of SaraB 0.2.2 on 2 different machines (Debian sarge & 
woody). Except of some paths both copies have the same configuration. 
I'm running simple daily differential backups and a full backup each week:

----
full1
diff1_1 full1
diff1_2 full1
diff1_3 full1
diff1_4 full1
diff1_5 full1
diff1_6 full1
full2
diff2_1 full2
diff2_2 full2
...
----

On my sarge everything runs fine. On woody SaraB doesn't get it right. 
The first full works perfect, the first differential not:

----
Top line of rotation.schedule: diff1_1 full1
Number of fields: 2
Creating a full-backup on the virtual-tape named: diff1_1 full1
...
Creating virtual-tape directory... mkdir /_backup/diff1_1 full1/
Moving files to the correct virtual-tape...
mv /_backup/.sarab_temp_workdir/20040915_1924.1.dar /_backup/diff1_1 full1/
ERROR: Error when moving the new archive. The attempted command was...
mv /_backup/.sarab_temp_workdir/* /_backup/diff1_1 full1/
----

Any help would be appreciated.
Thanks in advance,
Joergen.
