curses problem in konsole, new escape sequence not implemented

[jlittle]

$ echo -e "X\e[20b"
X

The X should be repeated 20 times; in an xterm it is. The problem is not that konsole does not support this sequence, but that the default terminal type in $TERM, xterm-256color, has changed from 17.10 to include this "rep" capability, perhaps with a new version of ncurses that landed recently, and konsole doesn't handle it. Any programme linked against ncurses, however ancient, will have problems running in a konsole in 18.04 as ncurses might optimize a string of repeated characters to use this.

A simple work-around is

infocmp | sed 's/rep=[^,]*,//' | tic -

That just compiles a new terminfo entry without the rep capability and writes it to $HOME/.terminfo, where ncurses programmes should find it.

Telling KFN this isn't much use, I imagine, so my real question is "Where should I report this?" I'm not sure it's a konsole bug; konsole seems to be at the same version as in 17.10, and the new capability should be implemented in some library deep in konsole's dependencies.

Google didn't find this for me when I first investigated, but maybe my search terms lacked the understanding I developed. Anyway, today, I found:

Is this fixed now in 18.04?

Not as of this morning. I just updated my 18.04 install (over 1100 updated packages and just over 100 new packages; haven't updated that VM is a while!) and

echo -e "X\e[20b"

still produces a single X.
