Revision: 42573, Tested in Ubuntu Linux QT 4.4 and QtWebKit.

Memory leak appears when creating and deleting elements, which match a style in
a stylesheet, which also uses one of +. [], or :first-child selectors.

Note that it does not occur if the attribute selector is applied to a element
selector, such as a[attributename] {}.

See the attached test case, which generates and removes elements, which match a
simple style in a stylesheet which also uses the aforementioned selectors. The
memory usage of the process grows linearly and never stops growing. When the +.
[], and :first-child selectors are commented out, this leak does not occur.
