Kmail vs. Thunderbird

[Valter Mura]

Hi All

so, again, the old, (in)famous issue.

System:
- Kubuntu 64bit 12.10 updated
- KDE 4.9.2

I made a *fresh* installation of Kubuntu in a "virgin" hard disk, setup the 
entire Kmail with all my accounts (everything is kept to server, so I don't 
have problems to lose something).

Nepomuk has made its work, indexing my folders and now is quiet.

The accounts are syncronized, Kmail is quiet. the "google-akonadi-contacs" 
plugin is working, so I can see my contacts in the addressbook. But.

But, I cannot get working the address autocompletion when composing a message!

So, even if now my system is quite new and works well (as fast as I expected), 
I'm seriously thinking of migrating to TB and have full-working system...

Please, give me suggestions for not take this irreversible decision.

TIA

Ciao
