MiniProjectTargetSelector popup shows incomplete information

The popup of the MiniProjectTargetSelector contains only two lines of text "Project: ProjectName" and "Build: Buildname" and nothing else.

Steps to reproduce:

1) Uncheck "Window>Show Mode Selector"

2) Close creator

3) Open creator, passing the project's .pro-file at the command line.

4) press Ctrl-T to show the MPTS popup.

Showing the Mode Selector and then hiding it again restores the popup to its usual appearance with the options to select projects/builds/executables.

Starting creator with the Mode Selector visible also works.
