Ported KonqPopupMenu away from xmlgui to make things debuggable (we had code that dynamically created XML, and then passed it for gui merging with KonqPopupMenu's own generated XML, that was too much magic and headaches).
There are now unit tests for KonqPopupMenu, and its code has a bit less magic hacks than before.
There is no more KonqPopupMenuPlugin though, but I'm happy to re-create it once there's a real use case for it.
