In Fedora 16, I have noticed for a number of weeks now that whenever Ilog
in, there are launchers on the task bar for konqueror and dolphin. I have
tried repeated to get rid of them, but every time I log back in, they are
there again.

How can I get rid of them once and for all?

Same here (Fedora 15 + KDE 4.7.1).

I was able to remove this launchers by editing $HOME/.kde/share/config/plasma-desktop-appletsrc and removing the relevant lines in the configuration of the "tasks" plugin, but clearly this is only a dirty workaround.
