Evolution: "Error writing line to bin file..."

[Slack006]

Hey there Jedis! Evolution was working great for me until today. Now, when I try to get mail, 2 of my accounts ask for the password (which had been previously stored), and then return the error, "Error writing line to bin file..." Has anyone seen this one? Any ideas where I may look towards a resolution for this f-ed up problem?
