i. e. this was fixed 91 commits before bogofilter-1.2.5.rc1. I don't know if the commit (Git cd33fc00802a75fe7b3b8a967bf879f7bc33c320) works standalone or only in context, and I'm not researching this because for me as upstream maintainer, this is done with the 1.2.5 release. => I think someone should package 1.2.5 for sid/unstable... more than half a year after its release.
