That should not happen. Did you get that message:
Opening output file test.avi: Input file format not recognized

That try using "lavtrans -o output.qt -f q input1.avi input2.avi" seems
that you cannot specify Quicktime and use a avi file extension.

Right that is much to small. And I have no idea why it should break
there. Except maybe a full harddisk. 

If lavtrans crashes a backtrace might be intresting. 
Were both files created with the mjpegtools ?
Can you try to decode each file with "lav2yuv file.avi | yuvplay -c"
And see if all frames are decoded properly, so the number of frames
printed out by yuvplay is the same as you get from lavinfo. I fear that
a frame could be damaged. 



auf hoffentlich bald,
