Yup. I suspected as much. The fact that we've got two versions
of curses and two sets of terminfo files on Solaris is fraught with

But I don't think it's using anything from the Solaris supplied files.

What needs to be done to get the desired behaviour in this latter case?
I'd start by checking the terminal description: if you're using anything
from Solaris itself, that's a problem.  infocmp would show where it's
read from (and interesting things like "bce" which are likely problems).

I truss'ed both the version 5.7 and runs, and they
are both getting their terminal description from


(which is the one from ncurses; I just used LD_LIBRARY_PATH
to test the Python script with the older ncurses libraries).

Here's what the ncurses version of infocmp says:

I'm not sure how to read this. I don't see anything related to "bce".
Any red flags for you with this terminfo file?

A couple more data points:

1/ I see the same behaviour in both gnome-terminal and xterm.
2/ We currently have an older version of vte (0.42.1) in Solaris.
    I googled around and discovered:
but neither truss output showed anything related to vte. so that might be
    a red herring.

Thanks for looking at this.
