Okay, this lends support to the theory that the crash is actually
happening in "scan" operation, rather than in some later part of the
amcheck-driver/taper process.
(Were there any error/warning messages written to the amcheck-device log
file for that run?)

Yeah, it might well work, and if so -- and if you don't care which
tape(s) are used next -- then simply switching to taper_traditional
would probably be the easiest approach to getting new dumps actually
written to tape....
If the order the tapes are used does matter to you, I think it should
probably be possible to fix the bug in taper_oldest (oldest.pm) to get
it working (but I'm not really sure how much debugging effort it will
involve...).
If you are interested to attempt that, the next thing I would check is
to see what happens with -otaperscan=taper_lexical (assuming that is also
defined in your amanda.conf). The "lexical" and "oldest" algorithms
both use the tape-drive inventory (while "traditional" does not), so
that test will help narrow the problem down to just "oldest" or to the
tape-inventory part of the code....
