Logging; how to find corrupt media file that crashes Kodi ?

SSH into the box and run "tail -f /storage/.kodi/temp/kodi.log" and watch the output on-screen stream past. When it stops, Kodi crashed.

The correct path is always /storage/.kodi/temp/kodi.log .. just start the tail, then start the library scan, and when Kodi crashes the output will stop at the point where it crashes. Use a large scroll-back buffer in Terminal.app or PuTTY (or whatever SSH client you use) and the copy/paste to pastebin and share the log. You cannot stop the tail and use the built-in paste, as by this point Kodi has probably restarted which will generate a new log file.
