Thank you for the quick follow-up, Andreas. There's no pressing need for an immediate upload. I'm just a user who wanted to help Debian be as polished as possible.
I'm glad you found the solution ultimately lies in blends-dev. Please note I filed a similar bug (#1011982) against the science-config package. If both my reports are caused by the same issue in blends-dev, maybe you can create a bug there and close the two separate bugs (or however Debian handles such cases). Thanks again.
