Hello and thanks for your report.

At first I could not reproduce your issue on amd64, Debian Testing with
Gnome3. However with another minimal Debian Sid i386 system and Openbox
I see the same error message.

        Error during recording: no element "appsrc"

Although byzanz depends on libgstreamer-plugins-base1.0-0 another
related package, gstreamer1.0-plugins-base, is not automatically
installed. I am not sure yet why libgstreamer-plugins-base1.0-0 does not
depend or recommend this package and whether applications must add a
dependency on it manually. I will discuss this matter with the
maintainers of gstreamer in due course.

In order to make recording with gstreamer and flash output work, you
also have to install gstreamer1.0-plugins-good and gstreamer1.0-libav.

I suppose once essential base plugins were moved to
gstreamer1.0-plugins-good and gstreamer1.0-libav otherwise I can't
explain why this was working in the past.

In short:

apt-get install gstreamer1.0-plugins-base gstreamer1.0-plugins-good
gstreamer1.0-libav

should do the trick. I intend to depend on these libraries in the future
to ensure that byzanz will work under all circumstances. I am lowering
the severity to serious because the package is not completely unusable,
ogg encoding and saving to gif works without those missing packages. Of
course this is still a release critical bug.

Regards,

Markus
