[Qgis-developer] problem with QGIS 1.7 "--snapshot"?

[Jim Hammack]

I have a simple project which includes a BlueMarble geotiff background, 
a shapefile of U.S. state boundaries, and several shapefiles of 
projected tropical storm tracks.  When I save an image of the map 
interactively using the "Save as Image" menu item, the resulting png 
file accurately reflects what is on the screen.  However, when I save an 
image from the command line using  "$ qgis tropical.qgs --snapshot 
snapshot.png" the BlueMarble image is shifted.  You can see the images 
here (I converted the png files to jpeg to save space/bandwidth):

I am running QGIS 1.7 built from scratch on a Slackware 13.1 system.  
All of the files are in epsg:4326.  I have the same problem if I use a 
TrueMarble geotiff in place of the BlueMarble so it seems like a problem 
with "snapshot" rather than with the data.  I used the same method last 
hurricane season with QGIS 1.6 and had no problems.

Any ideas?
