Problem with reply mail (HTML)

[Theet]

Since I updated Roundcube to version 0.9.0 stable and I reply a original mail then I don't get html for the original mail text, I see only raw text with html codes in it.

What is going wrong? I never had this before (since version 0.7.0 and later)

I have found the problem: it's the plugin "'scheduled_sending".

When I activate this plugin in main.inc.php then the reply mail will not show in html when I klick on reply.
