After a bit of a hunt, I found this in /etc/mc/mc.ext

# .tar.lzma, .tlz
regex/\.t(ar\.lzma|lz)$
      Open=%cd %p#utar
      View=%view{ascii} lzma -dc %f 2>/dev/null | tar tvvf -

:) I'm not exactly expert on mc regex, but I can't see what the problem
is.
I also tried renaming a .tlz to .tar.lzma. After doing this, no problem
opening it, and no problems with mc not recognizing it as a compressed
tar
file.

Can anyone see what the problem is? Anyone reproduce the problem?

:) Even better, any suggestions as to a fix that works?
Do you have the program "lzma" on your system? (I think lzma is
probably a symlink to xz nowdays)
Yes, I have /usr/bin/lzma, which is a symlink to xz. As I mentioned, if the
file is renamed from .tlz to .tar.lzma, it can be opened correctly, so the
system must be finding lzma. So I think the error must be in the regex used
to support the .tlz extention. I just can't see it...
Ah, sorry about that, I mis-read it.
No problem. Sorry about sending email direct - didn't realise that this
list doesn't have Reply-To set. I'll have to keep an eye on that one...
I think I can see the same problem now. I just tried to rename a
file.tar.lzma (which MC opened normally) to file.tlz and MC told me it
"doesn't look like a tar archive". However, when I manually ran the
command:

lzma -dc file.tlz  2>/dev/null | tar tvvf -

it listed the file's contents as you would expect. md5sum of both
files are identical.
That sounds like exactly the problem I'm seeing. Its not life
threatening <g>, but it is a pain, since both Vector and Zenwalk have
used .tlz packages in the past, and are only slowly moving to .txz.
I assume that it must be an error in the way the regex is structured,
but I certainly can't see it.
