ffmbc 0.6rc1 output to two files causes segfault

[GoogleCodeExporter]

Really simple example, this works:

ffmbc \
 -y -loglevel debug \
 -i combined.mov \
 -aspect 16:9 -r 25 \
 -an \
 -vcodec mpeg2video -vb 1000k \
  combined.vob

This seg-faults:

ffmbc \
 -y -loglevel debug \
 -i combined.mov \
 -aspect 16:9 -r 25 \
 -an \
 -vcodec mpeg2video -vb 1000k \
  combined.vob \
 -vcodec mpeg2video -vb 1000k \
  combined2.vob

The output codec doesn't appear to make any difference.
