AIUI the information is there it is just difficult to extract with 
simple tools
because you have to hande three seperate cases.

1: Source field not present: In this case the source version is the same 
as the
binary version and source package name is the same as binary package name
2: Source field is present but does not contain brackets: In this case the
source package name comes from the source field and the source version
is the same as the binary version
3: Source field is present and contains brackets. In this case the 
source field
must be parsed to produced both the source package name and source
version.
