Bug#910132: bittorrent-gui: bittorrent error (+ no autobugreport)

[Georg <HerrKrutsch@gmx.de>]

Package: bittorrent-gui
Severity: normal

Dear Maintainer,

-- System Information:
Debian Release: buster/sid
  APT prefers testing
  APT policy: (500, 'testing')
Architecture: amd64 (x86_64)
Foreign Architectures: i386

Kernel: Linux 4.18.0-1-amd64 (SMP w/8 CPU cores)
Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE=de_DE.UTF-8 (charmap=UTF-8)

What led up to the situation?
I wanted to download a debian live, so i had to install a bunch of
stuff, like bittornado-gui.

What exactly did you do that was effective?
Nothing. I just clicked on the [...].torrent link on the debian page, said
it to open with bittornado and did nothing. It downloaded it (i guess),
but still...

What was the outcome of this action?
... it opened an error-window with following content:

----------------------------------------------------
What outcome did you expect instead?
No error-window.
This is the first time I'm doing this and this confuses me. Did it
downloaded it, or not?
Is this error crucial?

With relaxed greeting
