Same bug in Ubuntu 11.10; I had to use the same workaround.

Title:
  usb-creator-gtk does not recognize Ubuntu PPC ISO images

Status in “cdrkit” package in Ubuntu:
  New

Bug description:
  Binary package hint: genisoimage

  How to reproduce the bug:

  1) install Ubuntu 11.04 on an intel-compatible PC
  2) start system/administration/startup disk creator (usb-creator-gtk)
  3) select an Ubuntu/PPC 11.04 ISO image...
  4) ...but the ISO file does not appear "selected" as expected (selected dialog remains empty).

  This is a long-term bug (I already experienced it in Ubuntu 9.04 and
  9.10), due to limits of "isoinfo" utility contained in the
  "genisoimage" package.

  Apparently, usb-creator-gtk verifies the correctness of the ISO image calling:
  /usr/bin/isoinfo -J -i /tmp/natty-desktop-powerpc.iso -x /.disk/info

  but isoinfo 1.1.11 complains "Unable to find Joliet SVD".

  Mounting the same PPC ISO image as looped filesystem works OK (the ISO
  image mounts OK and its .disk/info file contains "Ubuntu 11.04 "Natty
  Narwhal" - Release powerpc (20110427.1)").

  Funny, if I change /usr/bin/isoinfo with a shell script printing the
  "Ubuntu...powerpc..." string, the usb-creator-gtk works OK and
  correctly creates the USB startup disk.
