The fourth attempt failed:
I tried with Unetbootin from my production system (Ubuntu 12.04.5 LTS),
but it failed with the same symptom.

The fifth attempt succeeded:
First I cleaned to pendrive to decrease the risk of 'gridlock'.

Done, but you should also
check for the line 'dd: writing '/dev/sdd': No space left on device',
which means that the whole device is wiped. (Look a few lines above ^)

I started to think that my iso file is bad,
b66f9a0a87289be57cb3eb84f153c01d vivid-desktop-i386.iso

sudo mkusb-nox /media/multimed-2/test/lubuntu/vivid-desktop-i386.iso

And the pendrive works as it should :-)
(Some of you might prefer the GUI of mkusb to the command line interface
of mkusb-nox. But the programs do the same things behind the curtain.)
-o-
I'll try again later to make a working pendrive with Lubuntu 15.04 using
Unetbootin and the Ubuntu Startup Disk Creator ...
Best regards
Nio
