Ubiquity wants to unmount the Live USB

[Mélodie]

Using Lubuntu Trusty with Ubiquity 2.18.7

While booting to a USB live to perform an installation of Lubuntu Trusty 14.04, after the first steps, choose language, up to "prepare installation", I am prompted to unmount the /dev/sdb partition, which is where the session itself is started! This seemed to me a bit puzzling so I decided to come report about it. (This is a windowded message).

I attach here after a file where I added the output of the "mount" command, as well as a full lshw output. And here is a small screenshot of what I see:

Thanks for fixing it.
