The problem seems limited to a very big local Inbox folder. My Inbox collects mails from three POP accounts and is 178 MB. One of the accounts is configured to "leave messages on server".
Now I found a "solution" for me: it's comment #4, but slightly modified: I shut down evolution, renamed Inbox to Inbox2 (and Inbox.sbd to Inbox2.sbd). I deleted all *index*, *meta*, and *cache* in .evolution/mail/local/ and restarted evolution offline. To my surprise all messages in Inbox seemed to reappear (from where??). But clicking on them showed "the message does not exist". Thus I selected them all and pressed Delete. This gave me finally an empty Inbox and a 178 MB Inbox2. Since then I moved/copied/deleted hundreds of mails to and from Inbox2 with no problems.
So just don't let your Inbox grow to 100 MB or more. (this is a good advice anyway ;-)
