Ubuntu Evolution fix database disk image is malformed

Evolution 3.2.2 - eeep is broken!

I fire up Evolution after yet another system freeze and find no folders are present except the 'Search Folders > Unmatched'

Run from terminal to see whats going on

$ evolution &
[1] 3097
xxxxx@UbuntuSSDx64:~$ 
(evolution:3097): camel-CRITICAL **: camel_service_set_display_name: assertion `CAMEL_IS_SERVICE (service)' failed

(evolution:3097): GLib-GObject-CRITICAL **: g_object_set: assertion `G_IS_OBJECT (object)' failed

(evolution:3097): evolution-mail-CRITICAL **: Could not initialize local store/folder: database disk image is malformed

(evolution:3097): evolution-mail-CRITICAL **: e_mail_local_get_store: assertion `CAMEL_IS_STORE (local_store)' failed

Bit of debugging on

CAMEL_DEBUG=on

$ CAMEL_DEBUG=all  evolution  &
[2] 4677
xxxxx@UbuntuSSDx64:~/.local/share/evolution/mail/local$

Took a bit of a gamble here that folders.db is broken

~/.local/share/evolution/mail/local$ mv folders.db folders.db-

Yay, it works :) Click on the folder and out of it - (when clicking out you should see the number of mails in the folder quickly count up)
