This time it worked better. It was possible to install the bootloader,
and the Startup Disk Creator finished with a window

"The installation has finished ..."

It is still disliking the pendrive, but installed to it anyway. And it
finished nicely by unmounting the pendrive and the loop mounted devices
(which it did not with the i386 iso file as a source).

The pendrive is good. I can boot a[nother] computer with it, and the
live session works well :-)

The option to create persistence (and select the size of the casper-rw
file) has disappeared. It seems to be because of the -n option. (This is
not a problem for me, because I know how to create persistence manually.
But some beginners would appreciate the built-in option to create
persistence.)

So I flashed the amd64 iso to the pendrive again, this time without -n
and created persistence (I selected 1.5 GB).

This was a big step forward :-)

Bug description:
  [Impact]
  It is common to use usb-creator to write new USB devices with a version of Ubuntu which will then be used to upgrade or proceed with a new installation. In some cases, when using a specific match of versions of Ubuntu with an incompatible syslinux, the resulting USB device will show errors and not display the splash menu to use to select between Live and Install mode, or enabling extra options.
  This patch fixes this incompatibility by always using the syslinux version provided on the ISO image being used to write the USB device; which would always be compatible with the system to install if it's available. 

  [Test Case]
  1- Use usb-creator to write a new USB device with a version of Ubuntu with a different syslinux:
     Precise: use 13.10 or later.
     Trusty: use 13.04 or earlier.
     Utopic: use 13.04 or earlier.
  2- Boot on the USB, verify that the splash screen is shown and that you can get into a live session.

  [Regression Potential]
  This may yield cases in which the written USB device may be unbootable, due to having written syslinux data to the boot sector incompatible with the version of Ubuntu to be installed. USB devices may also be bootable but not show the splash screen and menu.
