I had the same problem and I believed that the file must have been prematurely truncated. In the end it worked fine with amrestore to grab the amanda file from tape
amrestore -C /dev/nst0 fs0 var
and then manually restoring the contents of that file (mine was a dump file).
gunzip -c /dumpfile/fs0._home.20050420.0 | restore -r -f -

I've had similar problems in the past for unknown reasons. In several instances running amverify <config> on the tape in question has been enough to correct the problem and allow me to restore.
Good luck.
