Problem with roundcube 0.6 after it was updated

[Spheerys]

Hi !

I just made an upgrade of roundcube from 0.5 to 0.6
For the olds mailbox, roundcube is working well
But for the new ones, there is a problem : the identity is not set in Roundcube
The login is working, but I can't send a mail without specify the field "From" (with my email address)
In my old mailbox, one loggued on roundcube, the "From" field is fulled with my mail account

On my new mailbox, if I try to set an identity, I have a server side error :
"An error blocked the saving"

What's wrong ?

Here the error in the log :

Code:

DB Error in /var/www/ispcp/gui/tools/roundcube/program/include/rcube_mdb2.php (285): _doQuery: [Error message: Could not execute statement]
[Last executed query: PREPARE mdb2_statement_mysql_3ff25d348dc3c0b07a40f5bc11da18f75c2a2cc28 FROM 'INSERT INTO identities (changed, `name`, `email`, `organization`, `reply-to`, `bcc`, `signature`, `standard`, `html_signature`, user_id) VALUES (now(), ?, ?, ?, ?, ?, ?, ?, ?, ?)']
[Native code: 1054]
[Native message: Unknown column 'changed' in 'field list']

In fact, I can't add an identity even with an old mailbox...
