Comment 16 for bug 39744

I have done changes in foomatic-db upstream so that it can be built without the driver XML file with empty command lines, without driver XMLs for obsolete drivers, and/or even only with driver XMLs for drivers which are recommended for at least one printer. In the newest Ubuntu package I have built this foomatic-db with driver entries for obsolete drivers and with empty command lines excluded. So the problem of printer setup tools breaking on driver XMLs with empty command lines should be solved by that. But note that this is more a workaround than a fix, the setup toools need to be fixed as suggested in my two previous comments.
