Setting Calculator to Super+C keyboard shortcut is ignored and Dash Photo lens gets opened instead

[grofaty]

Hi,
Three days ago I have cleared my Ubuntu 14.04 Desktop 32-bit from my PC and fresh installed Ubuntu 16.04 Desktop 32-bit.

One of the first thing I do is create keyboard shortcuts. So System Settings | Keyboard | Shortcuts tab | Launchers selection | Launch calculator and double click on item and select Super+C shortcut. Close the settings window. Press Super+C and instead of Calculator "Dash Photo lens" opens up. I don't need this shortcuts to lens (I don't really see the usefulness of lens for my workflow). I aways have had Super+C in previous versions of Ubuntu set to Calculator and also on my other computers also Windows I have Super+C for this purpose.

Any idea how to override this Dash shortcut?
Thanks
