Obviously if people mess with their PATH they might get weird results like starting drkonqi4, but that's simply their problem.

If anything, I'd rather use a special variable rather than PATH.  Putting things onto PATH that weren't named with that in mind is asking for trouble, IMO.

Maybe "KCRASH_DRKONQI_EXECUTABLE"?
