Version: (using KDE 4.2.0) OS: Linux Installed from: Ubuntu Packages Data loss in korganizer. I was trying to edit a todo event and got "Unable to edit item: it is locked by another process." error message. I renamed .kde/share/apps/korganizer folder and restarted kontact. I got empty todo as expected, but I couldn't create any todo "There is no resource available." When I restored the renamed folder, but I have empty todo list and still can't add new todos.
This doesn't apply to the akonadi version.
