ffmpeg2theora v0.27 quits early, using uncompressed avi with 6-channel audio

We are trying to create an ogv from a video containing a 6-channel audio file, but v0.27 quits after only a small portion of the video has been converted. v0.19 and v0.24c were both able to convert the whole movie with no problem, with the exact same settings. Here is the command line:

ffmpeg2theora-0.27.exe -o TEST.ogv -V4000 -A384 -c6 TEST_6ch.avi

When using v0.24c (and similarly with 0.19), it looked like this and the resulting file was fine:

[avi @ 0x37adb0]non-interleaved AVI
Input #0, avi, from TEST_6ch.avi':
  Duration: 00:03:42.54, start: 0.000000, bitrate: 535456 kb/s
    Stream #0.0: Video: rawvideo, bgr24, 1280x720, 24 tbr, 24 tbn, 24 tbc
    Stream #0.1: Audio: pcm_s16le, 48000 Hz, 5.1, s16, 4608 kb/s
  Resize: 1280x720
      0:03:43.04 audio: 388kbps video: 3452kbps, time elapsed: 00:17:09

Same exact input file and command line, using v0.27, but it always just quits after less than half the avi is converted:

[avi @ 0x34b150]ODML index invalid
    Last message repeated 5 times
