Hi,

when using the KIPI mechanism in my application,
I get log messages like:
kipi.library: This should only be invoked if the host application supports =
KIPI::Features ( HostSupportsMetadataProcessing ). If host application do s=
upport that, then this function should have been overridden in the KIPI hos=
t interface.

Note that my host application does not support HostSupportsMetadataProcessi=
ng.

What I understand is that KIPI::Interface::createMetadataProcessor() should=
 only be called by a plugin
if interface->hasFeature(KIPI::HostSupportsMetadataProcessing)

but e.g. in yandexfotki/yfwindow.cpp (and others) there is no call to hasFe=
ature()
and the method is just called without the check. (at least it checks if the=
 value returned is nullptr,
but in rajce/rajcesession.cpp it is not checked and might actually crash)

I assume this are bugs in the plugins, and the idea of the Interface class =
was to actually
must use a call to hasFeature(), right ?
