Comment (by pracine):

 I guess the clue here is the fact that ST_Box2D coordinates are encoded as
 float4 and Envelope as doubles. If I'm right, 1) the bug should appear
 only when there is many significant digits in the coordinates and 2) a
 PostGIS line geometry joining one of the two diagonals of a raster extent
 should present the same problem (Box2d should be different than the
 envelope). To verify...
