           Summary: Transcoding crash with new git master FAAC
    Classification: Platform
           Product: GStreamer
           Version: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: Uraeus at linuxrising.org
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Transmageddon segfaults when trying to transcode the gravity.mpg clip from
gstreamer.freedesktop.org/media/large (works when testing with some other
files).
This happens with ffenc_aac, so only triggers with new FAAC plugin (ported to
new baseclass).

Will also upload a GST_DEBUG log, but gdb backtrace below:

Program received signal SIGSEGV, Segmentation fault.
