I did some more testing with sizes because of the of number 8192 (=2^13), which is the height of the image that triggers this.

Here are the results:

16x8191 PNG image: No crash. [http://folk.uio.no/oyvinst/fdsbug21598/16x8191.png]
16x8192 PNG image: FREEZE [http://folk.uio.no/oyvinst/fdsbug21598/16x8192.png]
16x8193 PNG image: No crash. [http://folk.uio.no/oyvinst/fdsbug21598/16x8193.png]

It looks like this bug has something to do with height being exactly 8192.

I created various PNG test-images of different dimensions, they can be found here:

Of all these images, *only* the 16x8192 image triggers the crash/freeze. All images created in Gimp with transparency (don't know if that's really necessary..).

Hope this might help somewhat in tracking this down.
