Doesn't find correct terminfo entry

[hupfdule]

When starting vim from this appimage (version 8.1.2135) I get the following error:

E558: Terminal entry not found in terminfo
'tmux-256color' not known. Available builtin terminals are:
    builtin_gui
    builtin_amiga
    builtin_beos-ansi
    builtin_ansi
    builtin_pcansi
    builtin_win32
    builtin_vt320
    builtin_vt52
    builtin_xterm
    builtin_iris-ansi
    builtin_debug
    builtin_dumb
defaulting to 'ansi'

This doesn't happen with the vim distributed in Debian and it also doesn't happen with a a self-compiled vim (version 8.1.2136).

most likely, the terminfo database is not available in the sandboxed appimage. So use a builtin terminal description.

Ok. Thank you. Then I will do that.

And it is not likely to break when using vim under urxvt, but using TERM=xterm?

[Christian Brabandt]

it might. You have to try out.
