I confirm this behaviour. I'm experiencing this problem after splitting nautilus window (with ctrl+T command). The problem isn't inmediate, but after a while working with splitted window, copy/paste doesn't work.
In addition, I recently found some files on some other folder, and I realised that those files where the ones I was trying to paste. So, when I tried to paste "nothing happened", but now I see that the files where probably going to another destination folder. I cannot confirm this because I couldn't reproduce the problem, but if this is the case, **it's really critical**, as files could be copying to a different folder without the user even getting to know.

Sorry about my grammar errors :P
