xfsdump errors

[Andrew Mathews <andrew_mathews@xxxxxxxxxxxxxxx>]

I'm getting the following errors when running xfsdump on a Dell Latitude 
laptop running RH 7.3, 2.4.18-4SGI_XFS_1.1, and the following xfs rpms 
from oss.sgi.com:
xfsprogs-2.2.2-0
xfsdump-2.1.5-0
xfsprogs-devel-2.2.2-0
attr-devel-2.0.9-0
libattr-2.0.9-0
attr-2.0.9-0
dmapi-2.0.5-0
dmapi-devel-2.0.5-0
acl-devel-2.0.18-0
libacl-2.0.18-0
acl-2.0.18-0
This is using an HP DAT24e tape drive.

xfsdump: inv_core.c:79: get_counters: Assertion `((invt_counter_t 
*)(*cntpp))->ic_vernum == (inv_version_t) 1' failed.

I've searched the archives but not found anything relevant.
TIA-

I have yet to see any problem, however complicated, which, when
you looked at it in the right way, did not become still more complicated.
