I believe the problem is because GAE is returning Content-Type: image/x-png(according to curl, see below), and some browsers may not interpreting x-png as png (and hence downloading, as suggested by timh). I do not know why GAE is serving the file as x-png.
On my system (Chrome on Windows), it seems to only affect direct access of .png files in the static folder. My browser displays .gif & .ico files directly in the browser. Also, if the .png file is used in an HTML page, the image is displayed normally. When accessing your URL using Firefox on Windows, the image displays in FF. So, it appears that FF handles x-png as png.
