tgetent: warning: termcap entry too long

[Andy Walker]

I've been having a problem with GNU Screen Recently. The problem is
that, every time I run it, every shell is kind enough to inform me of
the following:

-----------------

tgetent: warning: termcap entry too long
$

-----------------

Which is definitely strange. Also, my END key doesn't work in VIM when
in screen (though, strangely it works on the terminal when in screen),
it just inserts 'F', which probably stems from the fact that it's not
being picked up as an escape character. Hitting CTRL-V END in my
terminal gives me "^[OF" which, when entered literally into vim
(CTRL-[, O, F) causes exactly this to happen.

It's probably also worth noting that the cursor keys, HOME and DEl
(not backspace) work perfectly well, and that this error doesn't
appear on my screen windows that do not start a shell, like a tail of
/var/log/messages or a vim session (even though the error still
persists in the vim session... reading $TERMCAP perhaps?).

-----------------
System Info
-----------------

OS: Modified Slackware Linux
Termcap/terminfo: There is an /etc/termcap file which is symlinked to
/etc/termcap-Linux. There is also a /usr/lib/terminfo symlink to
/usr/share/terminfo.
Screen version: This is present in 4.00.03 and the latest version in
git as of today (02/18/2009)
Bash version: 3.2.33

So, if I look at $TERMCAP from within screen, I see:

-----------------

-----------------

But there is no $TERMCAP set outside of screen, nor is there a screen
entry in my /etc/termcap, so my understanding is that Screen is
rendering this based off of what it finds in terminfo database? That
would make sense because configure defined TERMINFO in my config.h
when building screen. So what does terminfo have to say?

-----------------

At the suggestion of some of the fine folks in IRC, I grepped it for
'kend', in hopes that the information could prove useful:

-----------------
$ infocmp screen |grep kend
        kend=\E[4~, kf1=\EOP, kf10=\E[21~, kf11=\E[23~,

$ infocmp xterm |grep kend
        kcuf1=\EOC, kcuu1=\EOA, kdch1=\E[3~, kend=\EOF, kent=\EOM,

$
