        Bug 19907: REGRESSION(r34824-r34941): Reproducible crash trying to log in to MediaTemple.net Account Center
        <https://bugs.webkit.org/show_bug.cgi?id=19907>

        Clear exceptions set on ExecStates before returning from NPAPI
        callbacks, in order to avoid causing problems for the next script that
        executes.

        While fixing this bug, the question was raised of whether we are
        correctly propagating exception information back to the caller:
