I guess this isn't a bug in the technical sense, but it must seem like one for novice users. So it's more of a usability issue, but a serious and quite frustrating one for some people.

If you click "safely remove" on a device in dolphin, while having that same device open in dolphin, it won't work. It says "This device is currently busy". I remember I was quite puzzled by this years ago, until I figured out that, of course, dolphin itself was the one keeping the device busy.

It would be great if dolphin could just throw back to the home directory (or close a split screen) after being told to "safely remove" a device that is currently being viewed -- and only then try to unmount the device.

Reproducible: Always

Steps to Reproduce:
1. Insert USB stick or something
2. Open it in dolphin
3. Hit "safely remove" on the device entry in the panel
Actual Results:  
"This device is currently busy"

Expected Results:  
Dolphin should just close the view for the device and then unmount.
