Comment 3 for bug 807737

Set it to critical, as this can trigger false deletion in corner cases like the following:

Let's say you have these paths in your system:

  a/b/c
  a/b/d
  a/boo
  a/c

and having SD stopped, you remove "a/b", LR will inform the deletion of a/b/c, a/b/d, and a/boo (the later is wrong!).
