Hi,
I'm going through the list of open bugs in ncurses.

Actually, the rxvt-unicode terminfo file shipped in ncurses-base has
apparently not changed since it first appeared in 2005. The logs of bug
#270287 indicate that it was taken from an example file shipped in the
rxvt-unicode package. The current rxvt-unicode package in sid contains
an updated terminfo file in the doc/etc directory that however still has
this bug, AFAICS.
