This bug is fixed by commit 56f8add211a840faaed325bd16483b55da544e93
which is scheduled to be in 2.6.8, but was not included in 2.6.7.1.
I include it below.

Subject: [PATCH] Fix an error when assembling arrays that are in the middle of
a reshape.
It is important that dup_super always returns an 'st' with the same
->ss and ->minor_version as the st that was passed.
This wasn't happening for 0.91 metadata (i.e. in the middle of a reshape).
