Evolution dropdown menu for meeting does not work

[khul]

When adding a meeting in evolution, there is a dropdown menu to select the time. This only contains a limited part of the day, and scrolling (using the new "pop-up scrollbar") does not work. (It is possible to type in the time directly into the box.)
