Thanks for the report Parsifal. This specific issue looks very much like bug #677267, which was fixed in pyexiv2 0.3.0 (the latest release is now 0.3.2).

This is the output I get when running your example script against pyexiv2 0.3.2:

Xmp.digiKam.TagsList: <pyexiv2.xmp.XmpTag object at 0x27bf750> [u'Place', u'Place/Canada', u'Place/Canada/Yukon', u'Place/Canada/Yukon/Circle D Ranch', u'Vehicle', u'Vehicle/Aircraft', u'Style', u'Style/Pair', u'Adventure']
Xmp.lr.hierarchicalSubject: <pyexiv2.xmp.XmpTag object at 0x27bf790> ['Place', 'Place|Canada', 'Place|Canada|Yukon', 'Place|Canada|Yukon|Circle D Ranch', 'Vehicle', 'Vehicle|Aircraft', 'Style', 'Style|Pair', 'Adventure']

I am going to mark this bug as a duplicate of bug #677267, if you can test the latest release to confirm that the issue is fixed your feedback would be much appreciated.

I built pyexiv2 0.3.2, and it produced the correct result, as above.
Thank you!
