digikamimageplugins-doc-0.9.0 is already available from sourceforge.net, but not available in media-plugins/digikamimageplugins-0.9.0.ebuild Reproducible: Always
I'll handle that this weekend.
This is presenting additional difficulties and will take some more time.
digikam-0.9.2 (including current docs) is now in the tree and the plugins package is no longer needed. Let's move on with life. ;-)
