"Open Terminal Here" does not work in Run Settings

1. Open a project.
2. Build the project if you didn't do it yet.
3. Show its Run Settings.
   The executable's path is displayed there.
4. Right-click the path and select "Open Terminal Here" from the context menu.
   Expected: Creator opens a Terminal in the binary's parent directory.
   Actual: No Terminal can be seen. The GUI flashes once, maybe because it opens a Terminal view which disappears immediately.

If a Terminal cannot be shown in this situation, the context menu entry should be removed or hidden.
