I was trying to get kmail working since my upgrade to 4.10. I never got it working in 4.8.4 either, with similar errors. I looked online, but akonadi troubleshooting tips are all over the board. I found some for 4.3, and on the KDE wiki has one troubleshooting tip for "Can't read any details of some messages or big delays to read it" so I thought I would ask here.
When I opened kmail, it tried to transition to 4.10, and the first step was to start akonadi. It failed after a few minutes. Tests 1, 2, and 6 passed, tests 3, 4, and 5 (the mysql stuff) were untested.

No resource agents found.
Details: No resource agents have been found, Akonadi is not usable without at least one. This usually means that no resource agents are installed or that there is a setup problem. The following paths have been searched: '/usr/share/akonadi/agents'. The XDG_DATA_DIRS environment variable is set to '/usr/share:/usr/share:/usr/local/share'; make sure this includes all paths where Akonadi agents are installed.

Is there a config file that I should get rid of and just let it configure from defaults? I tried dpkg-reconfigure akonadi-backend-sqlite akonadi-server akonadiconsole but it had the same behavior after doing so.
