you should also try running png directly from sources.
assuming that this does not work, ...

it seems that here:
/sys/src/libdraw/readimage.c:103

		m = readn(fd, tmp, n);
		if(m != n){
>>>			werrstr("readimage: read count %d not %d: %r", m, n);
   Err:
			if(dolock)
				lockdisplay(d);

things are getting confused.  i think it would
be easier to debug if you added

	werrstr("");

right before the readn() and recompiled png.
i can't quite see how that error message could
result from reading an image.
