testAry = ["5", "7", "9"]
p testAry
numAry = testAry.collect { |n| n.to_i}
p numAry

Don't crash when a filter changes the subject of a message which results
in the attempt to remove it from the tree of subject threading messages
failing and the detached child looking for a new parent finding the old
parent as the new parent, which in turn results in the child being deleted
with the old (and new) parent, which is not a good idea, since it is
still referenced.
