This makes Smart Folders unusable for these users. Reproducible: Always Steps to Reproduce: 1. Have an IMAP account 2. under Tools / Account Settings / Server Settings, select: When I delete a message: (o) Just mark it as deleted 3. Customize the toolbar and add the "Compact" button. 4. Delete an e-mail in the IMAP account (it gets a strike-through line but is not removed from the messages list) 5. Try to press the "Compact" button Actual Results: The "Compact" button is disabled Expected Results: The "Compact" button should be enabled and pressing it should remove the marked-as-deleted message from the IMAP folder. The menu item File / Compact Folders does seem to work, but this is too cumbersome for daily use.

If Smart Folders is also the default for already existing accounts/installations, then this bug is a REGRESSION.

Not a regression. Dupe of a bug to make the compact button work with saved searches (which smart folders are a special case of).
