When a ogg audio clip is placed twice the following error happens:

$ ges-launch-1.0 --outputuri output.mkv --track-types audio --format video/x-matroska:audio/x-flac,channels=1,rate=44100 /tmp/sine.ogg 0 5 /tmp/sine.ogg 5 5

Adding clip file:///tmp/sine.ogg inpoint:0:00:05.000000000 duration:0:00:05.000000000

Debugging info: gstaudioencoder.c(882): gst_audio_encoder_finish_frame (): /GESPipeline:gespipeline0/GstEncodeBin:internal-encodebin/GstFlacEnc:flacenc0

Note the error does not happen if the clip is just used once.
