And indeed, rebuilding the identical package versions from source (to poke around and debug), fixed this problem for me.
As the system I am running is somewhat of a mix of stable, testing and unstable, could there be some incomplete package dependency that was not capturing a missing symbol in some related package? It's a pity that klauncher does not give a more detailed error message when loading fails. Maybe an strerror(errno) output in the right place might help here?
