Matt,

  Likely Quickbird_06m10.tif has more or less bands than the previous 
files, or band bit depth is different.   For example, don't try to 
include a 1 band 16-bit (e.g. gray scale) tiff in a VRT of 3 band, 8 
bits each (e.g. RGB color) tiffs.


  What does gdalinfo say about this file (and other files in the VRT)?

Best Regards,
Brent Fraser

That was it, thanks.

For some reason although they were all created from the same source and 
process (arcmap  export  selected area) some images are 8bit RGB and 
others 16bit grey (though still 3 bands). Weird.
