I got the fatal error see below while testing the new option autolabel, the configuration was empty and amcheck -s was ok.
The next tape Amanda expects to use is: 1 new tape. FAILURE DUMP SUMMARY: taper: FATAL Can't call method "lookup_tapelabel" on an undefined value at /opt/sfw/libexec/amanda/taper line 334.
