[Kde-pim] KDE 4.8, Virtuoso at 130% CPU for hours now - how can I help find the issue?

I will try that... and I hope to find the correct settings to deactivate 
nepomuk and virtuoso after kontact is being closed. 

On my notebook, I only run LXDE (on Mint and Ubuntu that consumes less power 
than KDE, other than on Suse - see our next Linux-Magazine), and I only start 
kontact, kate and other KDE stuff (great work you are doing!) when I need it. 
But I noticed that virtuoso-t and nepomuk are still running and ranking 
within the top five power consumer of powertop's list, even after kontact is 
closed and akonadictl has received its "stop" command. 

I guess I will have to write a small wrapper for me... and perhaps I will do 
another clean install. :-)

During the next days I am working on an online article for the magazine, 
showing some powersaving/monitoring tools that didn't make it in the article 
about power consumption. Perhaps I will try to do some application profiling, 
nothing big, but some tests, though.

I really hope that kontact won't be that much more hungry than thunderbird, 
but at the moment my hope isn't that big. 

I'll keep you updated...

:-)
