Andreas,

With commit #839677 digiKam and Showfoto now initialize Adobe XMP SDK at startup.

Damned, now digiKAm crash very quickly when an image is open in editor:

gdb /opt/kde4/bin/digikam --interpreter=mi2 -quiet

The program is running.  Exit anyway? (y or n) [answered Y; input not from terminal]
(gdb) Process exited

This is the code relevant from KEXiv2 private class destructor :

    // Fix memory leak if Exiv2 support XMP.
#ifdef _XMP_SUPPORT_
    Exiv2::XmpParser::terminate();
#endif // _XMP_SUPPORT_

Do you remember ? It's to fix memory leak from XMP SDK when KExiv2 instance is closed.

So i suppose than this call must be removed here and called in a wrapper method to cleanup memory at the right place in digiKam destructor
