Package: reportbug Version: 7.1.1 Followup-For: Bug #849564 Thanks for the hints, I found out that me having an abbreviated first name in ~/.reportbugrc was causing the same problem.
Reverting back to the full name (so with no "." in it) is a workaround, at least. -- Package-specific info: ** Environment settings: EDITOR="vim" DEBEMAIL="Philipp Marek <philipp.ma...@linbit.com>" INTERFACE="gtk2" ** /home/marek/.reportbugrc: reportbug_version "4.12.6" mode advanced ui gtk2 realname "Philipp Marek" email "philipp.ma...@linbit.com" no-cc header "X-Debbugs-CC: philipp.ma...@linbit.com" smtphost reportbug.debian.org mutt -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 4.8.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=de_AT.UTF-8, LC_CTYPE=de_AT.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages reportbug depends on: ii apt 1.4~beta2 ii python3-reportbug 7.1.1 pn python3:any <none> reportbug recommends no packages.
