           Summary: Web Inspector: Errors When Displaying XPathResult
                    Information
           Product: WebKit

          Priority: P3

Steps to Reproduce:
1. Evaluate the following in the Console of the Inspector on any web  page:
document.evaluate("//*", document, null, XPathResult.ANY_TYPE, null);
2. Attempt to Expand the Object Tree that appears in the Console.

Expected Results:
I'd like to see the properties of the XPathResult. The following was generated
using keys():
["resultType", "stringValue", "booleanValue", ... ]

Actual Results:
- A log message (not an error message) saying "Error dispatching:
getProperties"
- A blank error message shows up in the inspector's inspector

Further Issues:
- works => keys( document.evaluate(...) ); 
- doesn't work -> values( document.evaluate(...) );
- trying to access "snapshotLength" or "snapshotItem" and probably other values
results in a DOM Exception.  Are there problems with XPath in general?
