Cannot use a scalar value

[snyfir]

In my log file i have many messages like this :

[18-Oct-2010 19:31:04] PHP Warning:  Cannot use a scalar value as an array in /homez.18/autofrg/roundcube_0.4.2/www/program/steps/mail/func.inc on line 580

I think it can happen only in case of session corruption. So, we can prevent from warning, but better would be to find the reason of corruption. Is this warning reproducable? What PHP version? What DB? Make sure session table (and columns) are using UTF8 encoding.
