Hello, it's that time of year where I remove (i.e. archive) old entries in my various agenda files. One way I use to identify what I want to archive is to use org-sparse-tree, selecting [b]efore-date. If I do so, giving for instance "1 jan 2015" as the date, I get an error with backtrace in the attached file. Org is up to date from git. Thanks, eric -- : Eric S Fraga (0xFFFCF67D), Emacs 25.0.50.1, Org release_8.3.3-548-g99697a
