[RCU] Apache 403 Forbidden issues in 0.8.1?

I've actually been seeing the same thing in 0.8.0 and was wondering if 0.8.1 fixes the issue. I guess not.

I (also) haven't been able to dig too far in to it but I can usually get the client to stop flooding us with requests by deleting the session for that client's IP address in the sessions table in the roundcube database. Anecdotally it seems like there's a lot of repeat offenders: a small number of users/client IPs generating most of the 403s. I personally suspect something strange on their machines but I haven't been able to recreate the problem myself to really investigate well.

We're RHEL6.3, Lighttpd 1.4.31, php 5.3.3 (fastcgi), dovecot 2.1.9. Plugins: 'login_info', 'newmail_notifier', 'quickrules', 'cas_authn_opt', 'messagesize', 'sieverules', 'listcommands', 'contextmenu', 'copymessage', 'emoticons', 'vcard_attachments', 'new_user_dialog', 'dovecot_impersonate', 'help', 'vcard_attach'.
