Nautilus navigation buttons that replace the location bar, some times go missing when in side a folder

[Guruprasad]

The location button bar go missing when inside some folders whose name length is more than the size of the pane in a dual pane nautilus window, that the button containing the folder name cannot be displayed. The left arrow for moving across the location button goes missing and the right one doesn't work as expected.
