Using reportbug to follow up on reports has several disadvantages as not CCing other reporters, breaking threading and not allowing inline quoting in any way which is documented in bug report 677375 being marked as wontfix.

Please adhere to the following instructions on how to follow up properly.

  1. Download the message as a mbox file. There are two ways.
    1. The Web interface showing all the messages of a report adds links to the mbox version of each message. You can either use that to download all messages as an mbox file, for example;bug=677375, or just download the mbox file of the message you want to reply to, for example;mbox=yes;bug=677375.

    2. The package devscripts ships the program bts you can use to download the messages with bts show --mbox 677375. This downloads the a mbox file with all messages in it and saves in ~/.devscripts-cache/bts/677375.mbox.

  2. Import that message into your mail program (MUA) and reply as always making sure to add all relevant people to CC.
