mdadm gives segmentatin fault on wheezy. RAID array now incomplete.

[Hendrik Boom <hendrik@topoi.pooq.com>]

I ran

mdadm /dev/md1 --add /dev/sdd2

and got a segmentation fault.


april:/farhome/hendrik# cat /proc/mdstat
Personalities : [raid1] 
md1 : active raid1 sdb2[1]
      2391295864 blocks super 1.2 [2/1] [_U]

/dev/sdd2 used to be part of the /dev/md1 RAID1 array, but it went bad,
presumably becaues of a hard reset.

I did a 

mdadm /dev/md1 --fail /dev/sdd2 --remove /dev/sdd2

which appeared to work correctly, and after that

april:/farhome/hendrik# cat /proc/mdstat
Personalities : [raid1] 
md1 : active raid1 sdb2[1]
      2391295864 blocks super 1.2 [2/1] [_U]

april:/farhome/hendrik# mdadm /dev/md1 --add /dev/sdd2
Segmentation fault

What now?
