I do not use the ad blocker. Actually, I used an external ad proxy server
(privoxy), but that does not seem to matter. Anyhow, I do not see the issue you
are seeing at those forums, but I suspect what might be causing the issue. Can
you please try to generate a backtrace when konqueror starts eating the CPU ?
You can do that by attaching gdb to the running instance, e.g. gdb kdeinit4
<pid> or gdb konqueror <pid>.

I found out that the CPU spikes on my system were caused by the javascript code
kdewebkit executes to find forms on a webpage for automatic form filling. Not
entirely sure why that only happens intermittently at this point, but I suspect
it is related to the finished signal being emitted prematurely QWebPage.
Perhaps your problem is also caused by this as well.
