In Salix or in Fedora, it often has some issues.
Mint Cinnamon also can't unpack the file.
No issues in Fedora Gnome & Ubuntu.
Nor on Windows with 7-zip.

P.S.
This wasn't the only archive where Engrampa had issues with opening.
However, the others didn't show any meaningful messages.
It was simply trying and trying 'forever'.
One file left ... for hours.
