I have been using Konqueror for some time and am currently running v2.2.2 which I think is a little better than 2.2.1 but it still has those same issues. I resolved it on my system by doing this:
cd ~/.kde/share/config
cat /dev/null > konq_history
chmod 400 konq_history
cd ~/.kde/share/apps/konqueror
cat /dev/null > konq_history
chmod 400 konq_history
And of course you could do the above graphically from within konqueror file manager. I think those are the only two files...
Another thing I like about konq is you can disable the cache completely if you don't want anything cached. You can also be very selective about where you want to use Java and JavaScript. It can use the Netscape plugins but the plugin module needs some work. I think in KDE 3.0 this looks to be much better.
