Gimp 2.10 crashing every time I try to cut or copy

[Ofnuts]

Had a similar problem due to my clipboard manager (klipper). Fixed by telling it to not consider images(*).

(*) Images (and other big stuff) are not really copied to the clipboard, the copying application just publishes a handle, and pasting applications use the handle to copy the data (if ever necessary) directly from the source app.
