Just tried it.  Moved the two links out of the way.  Ran netscape.

With those links in place, it works fine.
(Note that this is the US-only version of netscape, installed using a
package copied from www/communicator with the md5 modified, and the
file already pulled down via the form on the netscape web page).

Ah... I think I've tracked down the problem.
The version of communicator which the original package pulls down is 4.5,
exportable, from the ftp site.  The modified package uses 4.51, domestic.
One of the changes between Netscape's 4.5 and 4.51 tarballs when I built
the modified package was that Netscape removed the nls subdirectory.
Apparently, netscape still tries to open /usr/X11R6/lib/X11/nls.
Without the link in place, the first attempt done by our emul system
(the open in emul) fails, and since we don't include /usr/X11R6/lib/nls
in our X distribution, and since netscape's 4.51 tarballs no longer include
it (and, since our communicator/navigator packages will, inevitably,
move on to 4.51 or beyond, we can't rely on the tarballs containing said
directory), netscape crashes.

No matter what we think about the links, though, the distfile includes
them, and the netbsd patches don't remove them, so the PLIST _should_
include them.  Netscape is probably not the only program which tries to
open files in /usr/X11R6/lib/X11, files which might be in the linux_lib
package but not our X distribution.
