Did you compare the contents of the package with and without -j? I am
almost sure some of the successfully built packages are actually not
correctly built and some files are missing.

For example I remember having seen some python packages building one 
flavour after the other in different targets. I imagine this could
result in one of the flavour being overwritten by the other, and thus
not present in the resulting .deb file.
