> Andrew, do you have any suggestion how to patch this bug properly?

Consider the following example:

   table data IN "...": s <- [FROM,TO], d~DISTANCE, c~COST;

For fields FROM and TO a null value is not allowed and should cause
an error. However, for fields DISTANCE and/or COST it could be allowed,
that would mean missing data.
