NullPointerException in query "Beep"

Please help! when I execute the following XPath query against Xindice,

(//ClientProfile/propertySheets/ClientPropertySheet/properties/property)
[@id='icas' and self::node()='1234']

Xindice causes a Beep and the following stack trace :


java.lang.NullPointerException

What is going on here? What am I doing wrong?

The result however, is the desired one!
Go figure.
