Hi, this is an issue very similar to #93549. Uncompressed tar archives are detected by content as application/pdf, when they only contain a pdf file (or when their first member is a pdf file). Example test archive: http://arxiv.org/e-print/1312.3844v2 The bug can be reproduced every time: $ tar -cf test foo.pdf $ xdg-mime query filetype test application/pdf This seems to be specific to pdf files. If you replace foo.pdf with e.g. foo.tex, the resulting archive is correctly detected as application/x-tar.
Looks fixed by 10fc17ec61c5b5c6c0e6ea2c8d7a2123271d07e3 1312.3844v2: name: application/octet-stream data: application/x-tar file: application/x-tar *** This bug has been marked as a duplicate of bug 93549 ***
