As previously noted on KubuntuKDEMedia page, but now doubtful that it's due to those patches:
2. Unmount media's progress dialog is gone. By default, Ubuntu mounts USB media async, and it's already been discussed and agreed in Launchpad that this is the desired behavior. In Dapper, when unmounting a USB stick, it displays an Unmounting Media progress dialog, which stays there until all the data has been written to the USB stick. This progress dialog is missing from Edgy, making it REALLY easy to accidentally pull out the media before it fully syncs.
This is a pretty serious issue as far as data loss and corruption potential is concerned and should definitely be investigated/fixed before Edgy releases.
