Comment 15 for bug 564263

I had problems with Akonadi after adding google contacts to it, I think the default setup in Kubuntu is incorrect.

You are supposed to use Akonadi as the "standard" while a fresh install of Kubuntu has a file-resource setup for both Contacts and Calendar.

I can confirm this on 3 PCs, fresh install and adding google contacts, removing the file resource for both contacts and calendar and adding Akonadi resources for these have resolved the issue, this is also mentioned at:

http://userbase.kde.org/Akonadi

http://userbase.kde.org/KAddressBook_4.4

According to those pages it's a "migration" issue, but this is a fresh install of Kubuntu, so I guess it's some sort of default to use the file resources as standard instead of Akonadi.

Someone else had the same issue:

http://forum.kde.org/viewtopic.php?f=20&t=86053

So I guess some sort of package update that sets Akonadi as standard when first logging in to KDE rather than files for KDE Resources.

After this I've had no more problems with Kontact. Hope this helps.

Note before doing anything, I waited a few minutes after logging in to KDE, it was repeatable almost every time.
