Yes, that is a bug in the (very old) 0.7.2 of Debian. Additionally, 
these old versions cannot handle spare devices (after each assemble, you 
hae to add them manually). Use at least mdadm 1.4.0, better the newest 
(I believe 1.5.0). You do not need to recreate the array, simply stop it 
and (re-)assemble it after you have the new mdadm in place - and the bug 
and the wrong output is gone.

Had the same problem (that with the spare device) with SuSE 8.2 and 
Debian Woody...

Bye, Norman.
