Segfault when using 'segment' format

Summary of the bug: Consistent segfault when using the 'segment' format. It looks like everything's going fine for a little while but then it segfaults. I don't think the inputs are affecting it because I've tried with different inputs (files) and it still occurs. Maybe it's one of the segment_* option modifiers.
How to reproduce:

% ffmpeg -f alsa -i hw:0 -f video4linux2 -s 720x480 -channel 2 -i /dev/video0 -acodec opus -b:a 32k -ac 1 -b:v 275k -vcodec theora -r 10 -map 0 -map 1 -vf lutyuv='y=gammaval(0.55)' -f segment -segment_time 180 -segment_list_size 999999999 -segment_wrap 999999999 -segment_list segmentList.txt -reset_timestamps 1 videoSegment-%d.ogg

ffmpeg version: HEAD from a few weeks back. I can confirm that the above command does NOT segfault when using ffmpeg commit 1de8a4f7366540df307841b2688dd361c0e32a06

configuration: --enable-libmp3lame --enable-shared --disable-htmlpages --disable-podpages --enable-libopus --enable-libtheora --enable-libv4l2

AMD64 Debian Wheezy Xfce. All the dependencies to compile ffmpeg using the above configure flags were installed using apt-get with wheezy as the target.
