Description Higa 2019-02-17 07:45:09 UTC 
SUMMARY
shared-mime-info 1.11 includes 2 MIME types for Zstandard archive, application/zstd (RFC 8478) and application/x-zstd-compressed-tar.
When using shared-mime-info 1.11 and above, a Zstandard archive may be identified as application/zstd, and Ark incorrectly reports that no suitable plugin can be found.

STEPS TO REPRODUCE
1. Install the latest version (1.12) of shared-mime-info
2. Create a Zstandard archive: tar -c --numeric-owner -f - test_folder/ | zstdmt - > test.tar.zst
3. Open the archive using Ark

OBSERVED RESULT
Ark returns an error message: "No suitable plugin found. Ark does not seem to support this file type."

EXPECTED RESULT
Ark should open the archive successfully.
