Hello,
I have a small server set up to serve image tiles as raw binary files. The 'app' consists of a HTML canvas page which uses an XMLHttpRequest() to request tiles from the server, which serves the tiles as raw data, which is then displayed on the canvas.

The whole app (minus the canvas2.html file) can be found here:

http://dpaste.com/hold/1364821/

Initially, it was working and I was able to serve and display tiles on my Canvas. Now my application crashes whenever I attempt to access a tile. The output from DUB is as follows:

Running /tmp/dub/811755627/vibe...

I have no idea what the cause of this error is. Any advice on how to track this down would be appreciated.
