Yes, upgrades can be very bumpy. If you're still using the user you created in 
2009, with the same configuration files, I am not at all surprised that your PIM 
setup is shot. A great many changes have occured since then, and the migration 
wasn't smooth at all.

nope, with akonadi-related problems, akonadiconsole is your friend. However, I 
must warn you that used incorrectly, it can be very destructive.
As for the why, because its broken, I'd try to fix it by starting at its 
initial state (yes, I'm a programmer)

Nepomuk is used for file tagging, history and other fun things. For instance, 
it indexes all your music files (extracts the id3 tags) and you can use this 
desktop service directly as a music database via the bangarang media player, 
or the music:/ kioslave. As of 4.8 it is also used for mail indexing, and does 
the heavy lifting behind mail search (not the quick filter bar).

As I see it, since you're in a non-working situation, you have 3 options : 
a - create a new user
b - delete non-working config
c- switch to something else

C was very much debated here, I won't go into it.

a : copying data isn't a problem, just copy all non-hidden files. Copying mails 
& contacts: know where they're stored, and you're ok. App configuration can be 
a PITA : for every app you have to know the necessary files and where to place 

b : I did this several times, completely deleting all PIM-related config 
(sometimes including nepomuk). It involved a bit of manual setup after to get 
it working from scratch (I left the wizards disabled), but IMO it was worth 
This is best done from a tty (terminal) without the desktop running as your 
usual user.
first delete ~/.config/akonadi, then ~/.local/share/akonadi
then delve deep into ~/.kde4, and delete anything that seems related to 
akonadi/kmail/addressbook (the whole PIM). Be careful though, as korganizer 
might be keeping a calendar file in the ~/.kde4/share/apps/korganizer/ 
subdirectory, and you haven't said where your mails are (kmail might have them 
stored somewhere).
After this, since you're not actively using nepomuk, I recommend you nuke 
evrything related to it too. (most stuff can be reindexed anyway).
Then log in (GUI), and the default akonadi configuration should appear. You can 
then configure all resources as you need using system settings.

if you have customized apps, option b is a lot easier otherwise if 
reconfiguring all the apps isn't such a hassle, I'd go for option a.

I just realized that this thread went from 'addressbook not working' to nuking 
all akonadi/nepomuk configuration. Fun :)
As a sidenote : I really do recommend nuking nepomuk, because the nepomuk 
feeders got a pretty big rewrite for 4.8, and really many bugfixes for 4.8.2/3, 
so it should work well (at least it does for me, although granted I don't have 
nearly as many contacts).
And I cannot stress this enough : make backup of important data before playing 
It all comes down to : do you want to try fixing your KDEPIM, or migrate now to 
something else...


PS : I hope all this makes sense, it's kind of late :)
