I just received this error:
tail: unrecognized file system type 0x53464846 for ‘../../kodi.log’. please
report this to bug-coreutils@gnu.org. reverting to polling

I ran this command:
tail -f ../../kodi.log

From this folder:
/root/.dropbox/Configuration/AppData/Roaming/Kodi/addons/skin.eminence.2

ls -ahl of the file (I am root)
-rwxrwxrwx 1 root root 19K Jun 19 15:28 ../../kodi.log

I'm running bash on Ubuntu 14.04.4 LTS on Windows 10

Any other info you need, feel free to ask.
