I'd noticed similar complaint (via google, of course) for gentoo.  It's likely
that this is the same issue.  Gentoo's packager used "xterm-xfree86" as
"xterm".  That introduced a feature which is not implemented in gnome-terminal.
That's not a bug in ncurses, but a defect in their packaging.

Reportedly gnome-terminal implements some of the features which I noted here as
differences.  For instance (I noticed recently in the context of a bug report
which should have been forwarded to me), recent (?) gnome-terminal copies the
function-keys portion of this (and a quick check with Debian's version shows
that it does - partly).  None of that shows up in its documentation however.

The features which are an issue here are indn and rin.
