Nullpointer on ft:query if <index> element is missing in collection.xconf

[windauer]

What is the problem

ft:query throws a NullpointerException in the console if executed against a collection with an erroneous collection.xconf (the element was missing) while in eXide no error is visible.

What did you expect

A more meaningfull error message to get an idea about the underlaying cause.

Describe how to reproduce or add a test

Take any XML you like, create a collection.xconf for it without an element and afterwards run a ft:query against the XML in that collection.
