Pi3 - April 02-16 - Cannot export music library XML

Hi. Having an issue with exporting my music library as an XML using the option in SYSTEM>MUSIC>

Either output format (single or separate XML) results in a quick flash of the progress bar. If I select single XML I get the following content in the resulting musicdb.xml.

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

I managed to create a working XML in a previous version, but not sure where to look in the logs for any info on what may be causing this.

My music was scanned into the library from my external USB HD via creating a source from the MEDIA directory entry for it if that has any bearing.

Any ideas?

Yes, provide debug logs.
