worst update experience

In the continuing saga, you may recall that I had updated to kde- unstable,testing, but then had a problem with DPMS not working. I finally reverted (with some difficulty) to standard f18. Turns out the problem wasn't the kde update after all, it was an update of google-chrome-beta. So I decided to try kde-4.10 again. Not a happy day. First, the yum transaction just hung 1/2 way through. I had to kill it. Then had to rpm --rebuilddb. This left me with a massive amount of dups. After surgery to repair the dupes I got synced to kde-unstable,kde-testing with no reported problems. I tried logging in, but found a problem with wallet and wifi password. I tried logging out, removing ~/.kde, and logging in again. Tried several times, but each time it just looped on trying to create kwallet. Apparantly, there is some state stored outside of ~/.kde - but I don't know where. I verified that a test user account could login and connect to wifi. Finally I moved all of my home dir out of the way, and then I could login and create a new wallet OK and connect. Slowly moved files and directories back into my account.
