Warn before try to copy on filled MTP devices
Submitted by Luca Ferretti
It seems that Rythmbox don't check for available space on MTP device before trying to copy files on it.
Steps to reproduce:
- plug MTP device, start Rhythmbox
- let's assume you have 2 MB free on device
- try to copy a 3 MB track
Current results: Rhythmbox don't warn about non enought free space, but show the usual progress bar.
Expected results: Rhythmbox should show an error alert.
