Every time I start Thunderbird, I get this error:

enter image description here

The current operation on 'Trash' did not succeed. The mail server for account spamspam@gmail.com responded: [NONEXISTENT] Unknown Mailbox: Trash (now in authenticated state) (Failure).

I've figured out that it goes away if I create folders in my Gmail accounts called "[Imap]/Trash" and "[Imap]/Sent", but why are these necessary? Even if I tell Thunderbird to unsubscribe from them, it still notices when I remove the labels and starts popping up this error again.

One account also complains if I remove the "Sent Items" label.

In the Account Settings, Copies & Folders you can change the location of any of these, you can even set them to local folders.

They are already set to IMAP folders like [Gmail]/Sent Mail, but Thunderbird still complains if [Imap]/Sent is deleted. – endolith Mar 6 '11 at 16:44
The closest answer I found is this: forums.mozillazine.org/… I have never had this problem show up even when removing my folders on the mail server next sync of Thunderbird updates them. – jtreser Mar 18 '11 at 6:35
