> Now, this error seems very similar to IMAGING-21, but it's not quite the same 
> for two reasons --
> 1) the stack is somewhat different, and
> 2) the fix provided for that bug does not fix this issue.
> Now, looking at the file that triggers this issue, other tools throw a 
> warning for it --
> gimp says: Corrupt JPEG data: 2715 extraneous bytes before marker 0xe2
> xv says the same thing.
> convert from ImageMagick converts it with no error or warning.
> jhead says: Nonfatal Error : 'pod_tile_foundation.jpg' Extraneous 2715 
> padding bytes before section E2
> jpegtran says: Corrupt JPEG data: 2715 extraneous bytes before marker 0xe2
> ... so it seems there's something actually wrong with this file, but even so, 
> the image is there, and other tools can determine the dimensions of it, so in 
> theory sanselan ought to be able to as well.
> I'll include the somewhat corrupt file that is triggering this exception, as 
> well as the test case program (which came straight from IMAGING-21.)
> The test case also checks the two files that were included in IMAGING-21 just 
> to show that that problem was fixed (at least once I applied the fix included 
> there.)
