Description

If a plaintext file starts with "MOVI" Tika labels it as an SGI Movie.

The hex conversion for MOVI is 4D 4F 56 49 which is the same as the header for the SGI Movie file format

This SGI format isn't supported so any information from a text file starting like this would be lost. I've attached a simple file that should recreate the problem.
