It's really strange, because everything seems OK. If I do it by hand,
I get:

*mount storage=Tapelib slot=3 drive=1
Automatically selected Catalog: MyCatalog
Using Catalog "MyCatalog"
3301 Issuing autochanger "loaded? drive 1" command.
3302 Autochanger "loaded? drive 1", result: nothing loaded.

3305 Autochanger "load slot 3, drive 1", status is OK.

Now stopping the SD, to use bls:

Everything looks OK, but if I try a restore the "normal" way, the
load-unload game is starting again.

Can it be a catalog problem? However, dbcheck shows no problems.

And, by the way, I am using Debian/Squeeze with 5.0.2 (forget to tell
yesterday).

Many thanks,
  Uwe
