Baz, 

Being a careful (and easily rattled) old soul, I did not remove libke.so, but 
moved it to my data partition, so that I would have a chance to "reinstate" it 
if it was necessary.  Have not noticed any harmful effects - Kmail continued to 
work, opening and saving files.

Unfortunately, it did not have any effect on the "dire warning message", as the 
following dialog shows:

ak at supremo:~/save$ python3 save.py
KGlobal::locale::Warning your global KLocale is being recreated with a valid 
main component instead of a fake component, this usually means you tried to 
call i18n related functions before your main component was created. You should 
not do that since it most likely will not work 
ak at supremo:~/save$ 

There is no change as far as the little test script shows.  Perhaps I am too 
timid, but I copied back the libkde.so where it was, namely
/usr/lib/kde4/plugins/gui_platform/libkde.so

Thank you again for the interesting suggestion.

OldAl.
