That's a very good starting point to debug.
The bucket index is stored inside the OMAP area of a raw RADOS object.
(in a filestore OSD it's in the LevelDB),  I wonder if you have
corruption or something else awry. 
How many objects were in this bucket? The number from 'bucket stats' is
a good starting point.

Newer versions of Jewel do report OMAP inconsistency after deep-scrub, so
that would be a help in your case too.
