local delivery folders stopped working on uprade to 3.6.0

[Romano Giannetti]

I updated ubuntu from 12.04 to 12.10 (I am using gnome-shell and evolution) and evolution stopped working completely with local delivery folders. Each time I try to open one of the local mbox file, I have a bunch of errors of the style:

** (evolution:11783): CRITICAL **: e_mail_session_get_local_folder: assertion `CAMEL_IS_FOLDER (folder)' failed

and

(evolution:11281): camel-local-provider-WARNING **: Didn't get the next message where I expected (57226) got 0 instead

with in the end finishes with

(evolution:11281): evolution-mail-WARNING **: Failed to refresh folder: folder://1350771666.3837.9%40romano-asus/to_2012_07: Summary and folder mismatch, even after a sync

It's not the sporadic "summary and folder mismatch" which hunts evolution till the eve of times, because now nothing works around it (removing *.index, folders.db, etc).

This is a serious enough bug to be a show-stopper for me.

I found an hint googling but I am not sure if it could be relevant: https://mail.gnome.org/archives/commits-list/2011-June/msg09955.html

Anyone can shed any light?
