Running KDE 4.8.2 on Mint 12 KDE. When I start up, I get the following notification: "Local folders: unknown error (collection with the same name exists already)." Any ideas what might be causing this?

Please open "akonadiconsole" and see if you have "Local Folders" listed twice with the same name. The error stems up from the fact that Plasma is using PIM components to show events in the calendar. This error is unrelated to events, but occurs during this system's startup. Alternatively, if you're not using PIM, try unchecking "show events" in the plasmoid calendar's configuration.

Interesting. The first time I ran it, it crashed. The second time, it came up. There is only one entry for local folders, but it's pointing to the kmail folder. I removed it, since I don't use kmail (had problems with it, so I use Evolution). Now I'm getting "Mail Dispatcher Agent: Could not access the outbox folder..." errors. They crop up every few seconds. I stopped Akonadi and restarted, and the latter errors seem to have stopped. Thanks!
