digiKam have been compiled with Qt5Webkit. Under Linux you must use Qt5WebEngine instead as Qt5Webkit is not maintained well.

Thank for info, Qt5Webkit is the default on Gentoo, I switched to Qt5WebEngine and it works fine now. I'll file a bug on gentoo side to update the default use of Qt5WebEngine.
