[Bug 521311] Re: usb-creator doesn't refresh size error

[Daniel Lawrence]

This bug is currently occurring in the latest release ( 12.04 ),

This looks like a problem with usbcreator/backends/base/backend.py not
running the /backends/base/backend.py:140:_update_free function if the
target has been flagged as either NEED_FORMAT or CANNOT_USE.

By running the /backends/base/backend.py:140:_update_free function it
forces the recalculation of size requirements of the sources vs the size
of the target and then updates the GUI to show that the target is
acceptable.

** Patch added: "Patch to force the call of _update_free in  /backends/base/backend.py:140"

Title:
  usb-creator doesn't refresh size error

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

Bug description:
  Binary package hint: usb-creator

  While having a 6.8G DVD in my drive I attached an empty FAT32 4GB USB-Stick.
  After starting the usb creator it said something like "partition size [of usb stick] not sufficient" which is correct.
  Then I selected a karmic i386 .iso file which has about 700M. Now there comes the problem, the usb creator didnt "refresh" the file size of the installation source (.iso) which is expected to fit onto the usb drive. Instead it still had this error message and a disabled "Make Startup Disc" button.

  I worked around it, ejecting the DVD and restarting the usb-creator,
  so it had no 6.8G image preselected.

  I consider this a minor, but nice-to-be-rid-of, bug.
