[Bug 2079979] [NEW] 'file' reports improper mime type on text file

[Daniel Schwab]

Public bug reported:

The utility 'file' reports different mime-types depending on the content
length of a text file with just multiple times 'X' as content.

For a file with 5789792 times the letter 'X' as content the 'file' tool returns 'application/SIMH-tape-data' as mime-type.
With just 1 letter less (5789791) the tool return 'text/plain' as mime-type, which imho is the correct result.


file is version 'file-5.45' on Ubuntu 24.04.
