Hey @aPischel, thanks for reporting. You said:

tried to revert unsaved file 'untitled.py'

What do you exactly mean by this?

[aPischel]

So, my computer crashed overnight and after re-starting spyder, I opened a new tab, didn’t save anything and then selected ‘Revert’ as shown below. This is what caused the error.

Thanks!

Adam

Could you upload your image by dragging and dropping it directly here? Unfortunately, Github doesn't allow to send images through email.

Thanks @aPischel, now I understand what's happening. We'll try to fix this error in a future release.
