Smilies appear in emails after installation of chat zimlet

Hi all,

After having a problem with the latest zextras suite, I manually installed chat zimlet (as advised here : https://forums.zextras.com/zxchat/1684-problem-chat-zimlet-after-zextras-upgrade-2-6-0-a.html ). After that I am getting weird smilies into our emails. I have tried to disable any "display emoticons" option in chat preferences but the problem still exists. The only workaround is to completely disable chat.

Please inform me if you are aware of this problem and if a workaround (or fix) exists .

Regards,
Nickitas

Ps. My zimbra version is 8.0.8 OS and zextras suite is 2.6 .
