Ghostscript also creates such images (under some conditions i am not certain about)
Several examples can be found in this page: 
http://ronja.twibright.com/metropolis/dist.php

The image shows up for just a moment, then goes white. If I open the image alone in a \
new tab the tab title says 'PNG Image - 0x0 pixels'

If I run any of them trough the pngcheck \
(http://www.libpng.org/pub/png/apps/pngcheck.html) utility i get something like this:

bash-3.00$ pngcheck -v -7 flux_50m_small.png
File: flux_50m_small.png (24417 bytes)
  chunk IHDR at offset 0x0000c, length 13
    256 x 372 image, 24-bit RGB, non-interlaced
  chunk pHYs at offset 0x00025, length 9: 2834x2834 pixels/meter (72 dpi)
  chunk tEXt at offset 0x0003a, length 29, keyword: Software
    GNU Ghostscript 7.07
  chunk IDAT at offset 0x00063, length 8192
    zlib:  deflated, 32K window, default compression
  chunk IDAT at offset 0x0206f, length 8192
  chunk IDAT at offset 0x0407b, length 6766
  chunk IEND at offset 0x05af5, length 0
  additional data after IEND chunk

Note the last line, which is common for all the broken pngs.
