cannot login using chrome browser version 34

[wolfjohns]

I can login with firefox and Internet explorer into roundcube webmail version 1.0.0.
But when I try to login using the current chrome browser version 34 on windows 8 I get the message "Invalid Request! No data was saved."
In the apache log I see that I get a PHP warning when trying to login using chrome.

PHP Warning:  [1062] Duplicate entry '' for key 'PRIMARY' (SQL Query: INSERT INTO session (sess_id, vars, ip, created, changed) VALUES ('', 'bGFuZ3VhZ2V8czo1OiJpc19JUyI7dGVtcHxiOjE7c2tpbnxzOjU6ImxhcnJ5Ijs=', 'xxx.xxx.xxx.xxx', now(), now())) in /var/www/webmail/program/lib/Roundcube/rcube.php on line 1245, referer: http://webmail.acme.com/

If there is some resolution or has anybody else having this problem.

hi wolfjohns,

Check if you do not have a DNS problem on your server,
otherwise I do not know yet ... 

Yours sincerely
