Description (last modified by styx) (diff)
Ironically, I see it when I try to open a tarfile of mc's own git tree. I create the tarball with:
tar cvf mc.tar --exclude '*/.git' mc
and when I press [enter] on mc.tar, it shows me empty list of files.
I will attach a smaller one, with most files deleted. It opens in 4.6.1 just fine.

The bug is in get_compression_type() function. MC interprets the attached tar archive as LZMA-compressed file.
The first byte of file is 'm', and the following condition (src/util.c:888)
if (magic[0] < 0xE1 || (magic[0] == 0xFF && magic[1] == 'L' &&
magic[2] == 'Z' && magic[3] == 'M')) {
is true. That's wrong.

Aha, and you didn't believe me and blamed the tar & zip utilities. Glad we've got it fixed!
