"usb-creator-gtk crashed with SIGSEGV in _dbus_watch_invalidate"
because the error output contains
'Failed to connect to socket /tmp/dbus-(and a temporary file string)'
-----
The pendrive made during the attempt described above did not boot at all. I should add that I told usb-creator-gtk to 'erase the disk'.
I wiped the first megabyte (dd with zeros), used gparted to make a new partition table and a partition with fat32. Then I tried usb-creator-gtk again. I got the same or a similar segfault, but this time the casper-rw file was created and the drive could boot. There is even persistence now.
Conclusion:
Erasing a USB pendrive with usb-creator-gtk is not enough to make it work properly.
Wiping the first megabyte (dd with zeros) will make it stop and complain.
It is necessary to make a partition table. I made a partition and a file system too, did not test the other alternatives.
So to increase the chances to succeed with usb-creator-gtk, I recommend wiping the first megabyte and making a new msdos partition table, partition and fat32 file system.
Comment:
usb-creator-gtk should be able to do all that by itself, when told to 'erase the disk'.

So finally the program did its job, although it reported a segfault instead of normal termination.
usb-creator-gtk created the live part of the installer, but crashed with segfault and failed to create a casper-rw file.
I think it is Bug #915626
