Slight correction, the crash occurs with PNGs with any transparency
(rTNS or alpha). I just happened to use the tRNS image in my bug report,
but I originally noticed the bug on PNGs with an alpha channel.

It may also be worth mentioning that the crash occurs only when
ImageMagick is used to the display the PNG. Just visiting an image file
does not use ImageMagick and thus works fine, while insert-image (and
probably other stuff) does use ImageMagick and crashes.
