[Roundcube] Thumbnails not showing

I saw that thumbnails of images wont show in Roundcube. Normally this is a PHP memory configuration, but I couldn’t find any errors in the log of /var/log/php5-fpm.log or nginx´s error log.

Thanks for reporting the problem. This seems to be fixed in Roundcube 1.0.3, so the next update of Mail-in-a-Box will include that.
