Description of problem:
Mass reassignment of bugs from one person to another doesn't work. If REASSIGN
is the only change requested, then bugzilla does come back with... um, you
didn't change a thing (or something similar).
Version-Release number of selected component (if applicable):
Current Live Bugzilla
Sounds like the same thing in bug 188743.
