Alternatively, you could go ahead and update the install to 
2.4.4p1-02030716, then when the time comes to do the housekeeping, rm 
the backups in the holding disk and the correct index files, then add 
that line to your amanda.conf.  At that point, the problem is 
self-healing should it occur again in the future.

Theres a fellow named Murphy (he wrote that law) that will see to it 
that it does happen again, he is in charge of tossing the coin for 
the occurance date of all things fubared. :-)
