Nothing jumps out at me as obviously invalid MH format, but it's clearly 
been modified and reused at least a couple times. There's extra stuff 
that's not normally present in MH format.

For one, it looks like you renamed maildir's subdirectories tmp, new, 
and cur to xtmp, xnew, and xcur, but left them there, in what is now 
used as an MH directory. There are still about 900 messages in xcur, 
which would be inaccessible to anything expecting either maildir or MH 
format.

Mutt might be trying and failing to interpret those subdirectories as 
subfolders -- failing because they're not either maildir or MH format.

I suggest that you try to start over, make a new clean folder. Use 
something high-level -- maybe Mutt -- to copy the messages into a new 
place and leave all the other stuff behind. Then rename directories to 
end up with the new clean folder having the same old pathname.
