Description of problem:
During boot, udevd-work tries to run mdadm, but mdadm segfaults.  mdadm segfaults from the command line if run with the --export switch.  mdadm does not segfault if the --export switch is omitted.

Version-Release number of selected component (if applicable):
mdadm-3.0-3.fc12.i686

How reproducible:
Always

Steps to Reproduce:
1. Boot and watch the messages when/after udev starts
2. Or run "mdadm --detail --export /dev/md0" (for example)
  
Actual results:
Error messages during boot.  Segfault on the command line.
(See below.)

Expected results:
No error messages.  No segfaults.
