Internet accounts error

Question

Like some others, I upgraded to OS X 10.10 and my Messages, FaceTime and iCloud connections stopped working.  I tried to log out & back in to FaceTime - but FaceTime won't work.  My Messages no longer sends to iMessage users.  I tried System Prefs > Internet Accounts and I get a spinning beachball then the error:
Preferences Error
Could not load Internet Account preference pane.
I ran this command in the console (thanks Linc):
find ~ $TMPDIR.. \( -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 \) 2>&- | wc -l | pbcopy
and the result it posted to the clipboard was 996
Now what?

Answer 1

I have also followed the test steps of removing the specified com.apple. and iMessage entries from the KeyChain of this computer. I deleted the flash storage and ensured that my SOCKS proxy was not enabled.
I logged out and back in.  Then I tried to open Internet Accounts again - and this is what I got from the System Message Logs:
