 I will attach the !MrSid file that's causing the problem (I have lots of
 these, this is just one). Other rasters are working for me. And this
 !MrSid worked in MGOS1.0.2...Because of this, I'm starting 2 tickets - one
 here, and one on the FDO site (since it could be either one causing the
 problem). I've been in touch with Jason Birch about this, and he has the
 same problem with this file as I do.

Comment (by jbirch):

 Added link to FDO ticket.

 In my testing, it looks as if the MrSID is being parsed properly by the
 GDAL provider (CPL_DEBUG shows it reading the various levels), but I end
 up with a white image on my screen.

 Using the current version of OpenEV distributed with FWTools, I can see
 the image just fine.

 My understanding is that this image is in CANST-NB83-CSRS which I believe
 is the same as:

 http://spatialreference.org/ref/epsg/2953/ogcwkt/

 I tried setting appropriate map extents and referencing the image from the
 map (to see if it was not showing just because of the extents) but was not
 successful with this.
