error "UID THREAD: Invalid flag name in Search command"

When you click on the label, to see all messages that have this label, you get the error message "UID THREAD: Invalid flag name in Search command"
It seems there is a problem for filtering the label.

This is with Roundcube that comes with Kolab 3.1 Alpha, rpm package roundcubemail-1.0-0.7.dev20130809.git328876.el6.kolab_3.1.noarch

we have found another issue as well, that there is an endless loading issue when you click on an email in a label folder.
