David,
we think we've fixed this bug. The reason was that when mounting RO,
then re-mounting read-write, the orphan sub-system was not properly
initialized. The fix is available at the ubifs-v2.6.28.git tree. I've
back-ported all stable changes and fixes to the tree. You need this fix:

UBIFS: ensure orphan area head is initialized
When mounting read-only the orphan area head is
not initialized. It must be initialized when
remounting read/write, but it was not. This patch
fixes that.

However, I recommend you to incorporate all UBI/UBIFS changes since
2.6.28, because there were other bug-fixes.

Please, send us some feed-back about whether your problem has been
solved.
