This bug is also in Radar as <rdar://4233800>
This is split off from 4665. This is one of the many leaks found with these steps:
1. Build a development build of tip-of-tree WebKit
2. use run-webkit-tests --leaks

This one still sometimes occurs this morning (most of the other leaks from 4665 have been fixed).
I haven't caught this one in a single-test leaks output, but I saw it once today with the output of run-
webkit-tests --leaks.

Checked in a fix that should fix the leak described in this bug, as well as two others. The three bugs are
bug 4795, bug 4796, and bug 4797.
