Ah, I see what happened.
For some reason, your old mail format was MBOX. The mbox format stores all mails of one folder in one big file. For performance reasons, when you delete a mail from an mbox folder, the mail is not removed from disk, since that would mean the rest of the mails in the MBOX file would need to change position, which is very slow for large mboxes. You can however "compact" a mbox folder, which should remove all deleted mails. See also bug 94992.

I think having a "special" folder like inbox, outbox, drafts, trash and sent-mail in MBOX format is no longer supported by newer KMail versions, so you'll get problems with that.

The format KMail now uses is maildir, and that is the recommended format. In maildir format, each folder has three subfolders on disk (cur, new, tmp), and each mail should be one file in cur.

I suggest you use the new maildir format and import your old mails with File->Import Messages. If that does not work, there is another trick to get your old mails from the mbox files back: Create a new subfolder in KMail, which gives you the ability to chose MBOX format. Then quit KMail and replace the MBOX file which was just created with one of your old MBOX files (rename it to the correct name of course).

If that works, I think this bug can be closed.
