Fix bug:

Norris,

I realize this is probably a nuisance, but the following problem causes our
regression test suite to fail:

    js> foo = new Error("bar")
    undefined: bar
    js> foo.name Error
    js> foo.toString()
    undefined: bar

Our test suite expects:

    js> foo = new Error("bar")
    Error: bar
    js> foo.name Error
    js> foo.toString()
    Error: bar

I have not yet tried the debugger with the RC2 release, but I expect to get
to that later today.

I hope I'm not to late to influence the 1.5R3 release.

Thanks,

dave
