What do you call "prompted" here?
"Save or Open" dialog? KOpenWith? "There was an error loading the module"?

It does that already, see konq_factory.cc:141
But this only works if the "broken lib" is really broken, i.e. KLibLoader can
immediately detect a problem (like a missing dependent lib).
I think that the lazy-resolving of symbols means that some undefined symbols
are only detected when they're hit, at which point it's too late.
