Title:
  erase disk results in error message + 100% CPU hang

Status in “usb-creator” package in Ubuntu:
  New

Bug description:
  It has been already reported that USB-creator is broken on 12.10, with
  USB images not being bootable. However, I also use this tool for
  quickly formatting my USB pen drive before using unetbootin. However,
  doing so results in a weird error message popping up and a 100% CPU
  hang coming from udisks (see attached screenshots). In the meantime,
  USB-creator stays stuck on "Erasing" indefinitely and I have to
  manually kill the udisks-helper-* job in order to get full control on
  my machine back.

  This is a serious issue. Together with the non-bootable Live-USB, it
  makes this tool completely useless on my machine. From a user
  perspective, It does not feel very serious for a Ubuntu-branded app
  (cf. app icon).

  
  machine: Dell Latitude E6420
  system: Ubuntu 12.10 amd64
  package: usb-creator-gtk 0.2.40ubuntu1
