The regression risk for checking for NULL might be low, but the package uploaded to the precise-proposed queue is instead a new upstream version - 0.2.10 - which contains unrelated changes and for some reason switches the packaging from 3.0 (quilt) to 1.0.
Please upload again, without the unnecessary packaging changes (and more documentation of the new upstream release if you choose to upload it).
