Thanks for reporting this crash. This has been fixed in release-2.0 by:

commit f4513b4de104f1c6f40f7bbe0a4bd698340db805
Author: Anand Avati <avati at gluster.com>

    Do not failover readdir in replicate
    Backport of http://patches.gluster.com/patch/561/ to release-2.0
    Also, the failover version of afr_readdir_cbk is buggy and
    crashes when it is called after a failover inevitably

    BUG: 150 (AFR readdir should not failover to other subvolume)
    URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=150

and in mainline by:

commit 77d8cfeab52cd19f3b70abd9c3a2c4bbc9219bff

    Do not fail over readdir in replicate.
    If readdir fails on a subvolume, do not
    fail-over to the next subvolume, since the
    order of entries and offsets won't be same
    on all subvolumes.
