It's never a good idea to remove items from the thing
you are iterating over. Create a copy of dirs (dirs[:])
to iterate on then remove the items from the original
dirs.

It always amazes me how often the same issues come up in
rapid succession. We must have had 4 or 5 of these types
of errors in the last couple of months, and other times
we go for 6 months or more without it being raised! :-)
