Changes (by lutter):

  * status:  new => assigned

Comment:

 That's actually two bugs hiding underneath each other:

   * the segfault should not happen, period
   * augeas should accept a regexp like /(a|)/ to mean the same as /a?/

 For now, you can work around it either by using '()' for the regexp
 matching only the empty word, or use '?'
