Followup-For: Bug #911610 Control: found -1 10.8+0.20120427-16 I've also observed this behavior (i.e. lost files in some package, e.g. eldav) in stretch, so it's probably apel there, too. Could you backport the fix to stretch and open a stretch-pu request? If you send a patch, I can test the fixed packages in my piuparts instance in stretch.
Thanks. Andreas
