Control: tag -1 + moreinfo Hi,
This bug refers to an old (or ancient!) version of Calibre. If you're running Debian 10 (Stretch), please update this bug by confirming if it exists in calibre-2.75.1+dfsg-1 (version in Debian 9/Stretch). If that version is bad, please enable stretch-backports and confirm whether 3.31.0+dfsg-1~bpo9+1 is affected. Alternatively, if you're running buster/sid, please confirm if 3.39.1+dfsg-1 is affected. Thanks! Nicholas
