Here is another example of (probably) the same bug:

Adding -r 25 to the command line seems to be a workaround for
transcoding, but I don't want to transcode from command line. I want to
edit the file with the cinelerra "monty-version" that uses the ffmpeg
libs for reading the video files.
File 'avchd-1080i-sony-wrong-framerate.MTS' not attached - you can download it
