Did you have checked the configuration of your account? There is an option for each account, where to store "junk" and "drafts". Maybe the information inside this config is invalid and so evolution did crash at any action with these folders.
The config of junk/draft is at account-properties at the fifth tab and the option is called "special folders".
(Sorry, I have a native evolution language so I cannot tell you the english names to find the relevant items more exactly)
