kmail dying and killing my system - akonadi? or nepomuk? issue?

[Dave Stevens]

A couple of days ago I was using my F11 gnome system where I use kmail  
as pop client and ran some ordinary updates (including several kde  
updates) from the usual Fedora repo. Subsequently I got progressively  
slower and slower kmail and then my whole system bogged.

The current situation is that kmail is totally unusable, and as soon  
as I fire it up my whole system is on the verge of unusability.

My mail is tied up in kmail boxes that I now cannot access. I of  
course have work in progress that I can't get at.

There was a pretty good thread on this topic on the fedora-list and it  
was suggested that people on this list might have more info.

So what I think is happening is that somehow akonadi and/or nepomuk  
are fried, giving extremely slow (glacial) performance for programs  
that depend on them. I was able to see from a nepomuk failure message  
a link to a kde site where there were instructions for a workaround.  
This helped a bit and I will no doubt need to find those instructions  
again and get familiar with the process, because the fix is transient.  
For unrelated reasons I've had to reboot and every time I do I'm back  
in glacial terrain.

Can anyone (PLEASE) suggest a decent fix or provide more information  
about this issue?

TIA

Dave
