[MX Player] speakxj7:
crashes when viewing the file list, my best guess off the cuff is it is related to thumbnail generation (i saw options to clear, but not disable thumbnails).

if i use a different file explorer to select the file (and invoke mx player as the action), it plays just fine.

grabbed a logcat with adb:
