Console error when pasting with empty clipboard

[pascalwengerter]

Not a very visual error, yet worth preventing I suppose

Steps to reproduce

1. Press Ctrl + v on a freshly reloaded page (e.g. personal space root)
2. Nothing happens in the UI, TypeError: u is undefined error in pasteSelectedFiles on browser console

Expected behaviour

No console error, maybe display a message to the user about not being able to paste zero files? @tbsbdr could be nice, don't know of an app/OS that does this though

Worth mentioning that I can't reproduce this with Ctrl + x on an empty selection

display a message to the user about not being able to paste zero files

I would recommend to stay silent in the ui because users are likely to not expect a message at that point, because - as you say - they are not used to it.
