   I wasn't trying to make anything melodramatic.  I just spent time debugging 
a problem which turns out to be because the object returns a pointer but 
deletes that pointer on you apparently without warning.  The usage case was 
this [reduced]:

KCompletion *foo = combo->completionObject();
foo->clear(); // or anything else

It's really not obvious that this will happen since I never touched the 
completion object in any way between getting a pointer to it and then using 
that pointer.  This crash was reported to me by someone else who also 
probably didn't understand why it was crashing.

  Sorry, the completion stuff really is confusing.
