Yes. Konqueror and Kate are the only two applications affected from that 
change ( until now ).

Versions < 4.1 from those applications will fail when run against a kdelibs 
debug build from a 4.1 release ( or current trunk ). But they will work 
correctly agains a kdelibs release build. I have added a ASSERT. The code 
falls back to the old behavior in a release build.

I thought i had made that clear.

If that means they run correctly is up for discussion. They will probably get 
problems when the global shortcuts code is fixed regarding components 
handling.The code currently doesn't handle multi component applications ( as 
in kparts ). It assumes that all shortcuts will be registered and handled 
under KGlobal::mainComponent() or another component provided to 
KGlobalAccel::overrideMainComponent.

And it's not really only a global shortcuts problem. If someday someone 
decides to implement gestures for KActions ( some code is there currently ) he 
will probably very pleased with the changes we are about to make. 

Those changes ensure that each and every action is identifiable by a unique id 
consisting of it's component name and it's objectName ( the string provided to 
KActionCollection::addAction ).  It's currently not possible to have a 
persistent id for actions.
