I suspect this will be fixed by

You array currently has two superblocks on it, which will be confusing.
If you stop the array and then
mdadm --zero-super --metadata=1.0 /dev/sdb1 /dev/sdc1
the new incorrect metadata should be removed.
If you apply the above patch to mdadm (maybe get clean source with
git clone git://neil.brown.name/mdadm
then apply the patch and run "make") you should be able to assemble
--update=metadata and get a working array.
Thanks for the report.
