Also unexpected:

~ # cd /etc
etc # fgrep -R 131072 * 2> /dev/null
apache2/modules.d/10_mod_mem_cache.conf:MCacheSize 131072
sane.d/sharp.conf:option buffersize 131072
sysctl.d/97-kde-baloo-filewatch-inotify.conf:fs.inotify.max_user_watches =
131072


I have logged out and back in, to check for the effects on that window
asking for root password.  It did show up again, and now the
file 97-kde-baloo-filewatch-inotify.conf has been changed.

Going to try again, after removing 97-kde-nepomuk-filewatch-inotify.conf.
Back soon...
