I inadvertently filled up my /home partition with an over-sized virtualbox hard drive. I fell asleep and did not realize it filled up. When I awoke I had errors galore, mostly about UUIDs being invalid and kmail and akonadi could not read the folders in my dimap and it might be a permissions problem. I clicked okay about 15 times from the UUID errors and deleted the virtualbox virtual drive. I rebooted my computer and when I logged back in I got the same errors all over again. Something changed the permissions on my files! Kmail contained no record of my dimap folders. I looked in .kde/share/apps/kmail and the folders were not there. Did akonadi delete them? My filesystem is ext3, just so this is not thought to be a problem with ext4.
