Just after upgrading KDE 4.13 (running nicely) to 4.14 kontact crashes with the following message:
"The protocol version of the akonadi service is not compatible. Please make sure you have installed a compatible version (protocol version 37 has been found, at least version 44 has been expected) ... failes to load tags ... "
( I translated the message...)
I do not understand the message nor what I can do now...
"akonadi server protocol too old"
obviously the correct akonadi server version 1.13 has been stuck in testing and not been transferred to the official repositories....
installing akonadi 22.214.171.124 solves the problem....
No problem, glad you got it working.
