--- Comment #4 from Jeff Byers <jbyers at stonefly.com> ---
This problem occurs as a side effect of the fix for:

    Bug 1282390 - Data Tiering:delete command rm -rf not deleting
    files the linkto file(hashed) which are under migration and
    possible spit-brain observed and possible disk wastage.

tier_unlink() is freeing the xdata out from under the shards
causing the dict_*() segfaults. It looks like dict_unref()
should only be called when the dict_set_dynstr_with_alloc(,
DHT_IATT_IN_XDATA_KEY) path is taken.
