Remuxing cook leads to broken files

[Đonny]

Summary of the bug:
I have some real media file. I trim it by FFmpeg (loss-less), afterwards FFporbe refuses to give information about the file, and I cannot play it.
How to reproduce:
1) Trim the file

ffmpeg.exe -ss 00:04:43.2400000 -i RM.rm -t 00:08:33.5800000 -c copy -map 0 -threa
ds auto -y -map_chapters -1 trim.rm

I don't understand: How is this ticket related to FFprobe?
