Copied cells only post as .bmp in Calc

When I attempt to paste a copied cell value or formula in Calc, the only thing that will paste is a .bmp. I am using Libreoffice v.

I have experienced this problem with both Linux Mint17.3 and with Windows.

Is this a bug or a settings issue?

How do you do the copy, with keyboard, menu, context menu?

The problem is the same no matter how I copy – menu or mouse are the 2 methods I usually use.

Please try resetting the user profile, sometimes solves strange issues.
Usually it’s enough renaming/deleting the file “user/registrymodifications.xcu”, it affects all the options in Menu/Tools/Options, and the files “user/basic/dialog.xlc” and “scrip.xlc” are overwritten, additionally custom colors in “user/config/standard.soc” are lost.
