Hmm, I'm not sure what the permission issue might be... If you can come up with some steps to reproduce it, you can open an 'Issue' on the lnav github page and I can take a closer look at the problem. Thanks!
A good companion to glogg. Only problem is with permissions. Even if you run as root, the file browser is denied permission to open files in the log folder.
My /var/log/mylogs permissions are: drwxr--xr--x and the files: -rw-r-----
