Whenever I click a USB icon in the system tray and click the "Safely Remove" menu option, the USB is correctly unmounted---but since the last Fedora update (KDE 3.5.9-5) I now always get an error dialog afterwards with the caption: Error - kio_media_mounthelper and with the error message: The device was successfully unmounted, but could not be ejected Well since the device is a USB of course it can't be ejected. This is annoying and also confidence reducing (I now tend to do a df just to check that the USB is really unmounted).
After today's security updates were applied the problem has gone.
yay, thanks.
