Following Waldo's fix yesterday for reads/writes in deleted
KFileMetaInfoItem, I can now shut down kate cleanly, using File->Quit.
However, if I instead shut it down by clicking on the "X" in the
top-right hand corner of the window (the usual "make this window go
away button"), I consistently get the following 3 complaints 
(they occur in the order shown).

Knowing nothing about KDE internals (I am a compiler writer) I have no
idea if this is a Qt problem or a KDE problem.  Once again this is
with qt-copy, kdelibs and kdebase from CVS as of 20:00 GMT on 31 Jan
(thursday evening).

I hope someone can make sense of it from the trace below.
(31878 is the pid of the traced process; no other significance).
