yes, it's not unlikely that the interaction broke and I didn't notice (for me 
focus had been broken a long time on my multi-screen setup and I implemented 
the changes on the multi-screen setup).

In the old setup the window got focus after being mapped. Now that's no longer 
the case. The window gets mapped once the WID has been passed to ksld - which 
according to my testing seems to happen after the window gets mapped. Might be 
that Qt is "confused" when it gets the additional focus request.

Which part of the screenlocker? Greeter is really difficult to get at, but 
should end up in xsession-errors. If you want to test the interaction try the 
test application in the build directory.
