Title:
  Invalid PNGs crash Hugin

Status in Hugin - Panorama Tools GUI:
  Confirmed

Bug description:
  I came across some PNG images which would always crash hugin as soon
  as they are loaded.

  Digging a little deeper I discovered that the PNG file had been
  truncated (specifically... the last PNG IDAT chunk wasn\'t the number
  of bytes it should have been).

  Most image viewers I tried opened this file without a problem. Hugin
  should either load the image or (better still) give an error saying
  the image is invalid.

  This was only tested on windows. I have attached an example truncated
  PNG file.
