Are you sure that location is already an empty string, or do you only 
observe that PackagePath below is an empty string?

For adding a "midicsv" segment to the path of the URL represented by 
location, I would not use URLTransformer (I have my personal doubts 
about it), but com.sun.star.uri.UriReferenceFactory; something like:

UriReferenceFactory f = UriReferenceFactory.create(m_xContext);
XUriReference url = f.makeAbsolute(
   f.parse(location), f.parse("midicsv"), false,
   RelativeUriExcessParentSegments.ERROR);
if (sub == null) { ... error ... }
PackagePath = url.getUriReference();
   // assuming that PackagePath shall denote a URL
