Public bug reported:

After using the usb-creator-gtk program the resulting Ubuntu 16.04.3 stick is 
corrupted.
The error message when re-purposing the stick is:

"The driver descriptor says the physical block size is 2048 bytes, but
Linux says that it is 512 bytes."

It seems like usb-creator-gtk is using dd without specifying the correct
blocksize corrupting the USB stick.

I've now lost 4 USB sticks on two different computers that I now can't
format back to a usable stick.

Steps to reproduce:
Insert a blank USB stick into the USB port of the computer
Run usb-creator-gtk with an Ubuntu 16.04.3 ISO
Open gParted (parted, blkid, lsblk etc...)

"The driver descriptor says the physical block size is 2048 bytes, but
Linux says that it is 512 bytes."

try to clean the disk with
dd if=/dev/zero of=/dev/$USBSTICK bs=2048; sync

again check the disk with gParted (or other disk utility)
"The driver descriptor says the physical block size is 2048 bytes, but Linux 
says that it is 512 bytes."

USB stick is destroyed.
