11.0.6 has switched ix.io to our own paste server since ix.io was down, so just cat/pipe files to "paste" and you'll get a URL.
Uploading files sounds like you're copying the file over SMB? Has it been created in Notepad.exe? If yes this is likely a Windows line endings issue and will be solved by creating files with Linux line endings using Notepad++ or accessing the box via SSH and using nano (copy/paste the content to the screen) to create the file.
The file was actually created on CentOS with the default text editor and passed via SFTP.
I tried as suggested to create the file directly on Kodi and still it crashes.
