Missing icons in status bar

Hi,

I have 2 PC with ubuntu 14.04 (one with cinnamon and one with LXDE). In both I have this problem in Libreoffice v5.0.0.5, look at this screenshot:

As you can see some icons are missing ("+" and “-” in zoom control, etc…).

Is it a known bug or I can do something to solve it?

Thanks

What if you select Menu/View/Status bar?

it just disappears! (because it’s already checked)

Please try resetting the user profile, sometimes solves strange issues.

I tried that, but no luck.
