Incomplete error message: "$2" ?

[Gabriel Petrovay]

Using the following library module (lm.xq)
----------------
module namespace lm = "http://foo";
import module namespace bar = "file://bar";
----------------

and running:
zorba --compile-only -l -f -q lm.xq

Zorba issues the error: static error [err:XQST0046]: "file://bar": invalid URI literal: "$2": invalid authority for "file" scheme; raised at C:\Users\Gabriel\Work\28msec\zorba\src\zorbatypes\URI.cpp:667

What is the meaning of "$2"?

The error has also a wrong location (run with -x):
<location module='' lineStart='0' columnStart='0'/>

instead of smth like:

<location module='lm.xq' lineStart='3' columnStart='1' lineEnd='3' columnEnd='43'/>
