It seems likely that this is related to LU-11933, which is an LASSERT() on the MDS during migration because the object is missing. I suspect some kind of race condition, and where the -ENOENT is seen decides whether the test just fails with "no such file or directory" or triggers "osd_declare_dir_delete() ASSERTION(dt_object_exists(dt))".
