F28 - core dump in system libexiv2.so xmp handling about exiv2-raw-preview-rating-plugins

[whatdoineed2do]

This looks like a problem with XMP toolkit initialisation .. but the toolkit is included in in libexempi and also in libexiv2 - libexempi is linked against eog. The XMPMeta::Initialize() method is hit 3 times

The difference in symbol names may explain why an older version of exiv2 (0.25 or early 0.26) statically linked into this code works.
