Please either install debug libraries to make the backtrace useful or (even better) recompile current FFmpeg git head with "./configure --enable-libdc1394 && make ffmpeg" (likely needs libdc1394-22-dev, no FFmpeg installation required) and provide a full backtrace with symbols.
I consider it possible that dc1394 support in FFmpeg has not been tested for a year, sorry!
