I am perfectly aware of <https://wiki.ubuntu.com/Bugs/Triage#Apport_crash_reports> but besides the fact that this bug report refer to a a VirtualBox setup that existed only for testing purposes, neither Stacktrace.txt, StacktraceSource.txt and ThreadStacktrace.txt contained any sensitive information.

Since the "vboxvideo_dri.so" component is what really crashes, this isn't a bug in the "gstreamer1.0" package but in the "virtualbox" one.
