Thanks for the report. What happens if you edit the file
/Applications/Zenmap.app/Contents/Resources/etc/gtk-2.0/gtkrc, and
change the line

gtk-font-name="Lucida Grande"

to

gtk-font-name="Lucida Grande 10"

Still crashes ...

valentina:~ nilsonj$ sudo
/Applications/Zenmap.app/Contents/MacOS/zenmap_wrapper.py
Xlib:  extension "RANDR" missing on display "/tmp/launch-ZdeUX0/:0".
Segmentation fault

NB Running the .bin will produce a GUI, but the characters are all
off-codepage so they are not rendered.  Could be a codepage definition
problem?

Let me know what else you would like to try.

No, you get the boxes when Pango can't find its configuration files.
Because the Zenmap.app bundle can be run from anywhere, but GTK+ and
Pango require static locations in their configuration files, we write a
set of files to ~/.zenmap-etc on startup. Running the .bin directly
bypasses the creation of those files and the setting of environment
variables that cause them to be used, so Pango rendering doesn't work.

Try removing the .zenmap-etc directory (rm -r ~/.zenmap-etc) and let us
know if that works.

Also delete ~/.fontconfig. I found this Wireshark bug that is relevant:

Good to know.  Here's the result:

valentina:~ nilsonj$ rm -r ~/.zenmap-etc ~/.fontconfig
override rw-r--r--  root/staff for
/Users/nilsonj/.zenmap-etc/gtk-2.0/gdk-pixbuf.loaders? y
rm: /Users/nilsonj/.zenmap-etc/gtk-2.0/gdk-pixbuf.loaders: Permission denied

rm: /Users/nilsonj/.zenmap-etc: Directory not empty

valentina:~ nilsonj$ sudo rm -r ~/.zenmap-etc ~/.fontconfig
Password:
rm: /Users/nilsonj/.fontconfig: No such file or directory

Run as root ....

valentina:~ nilsonj$ sudo
/Applications/Zenmap.app/Contents/MacOS/zenmap_wrapper.py
Xlib:  extension "RANDR" missing on display "/tmp/launch-ZdeUX0/:0".

(Waits about 60 seconds for GTK+ to load) ... SUCCESS! :)

Subsequently run as user ....

valentina:~ nilsonj$
/Applications/Zenmap.app/Contents/MacOS/zenmap_wrapper.py Traceback (most
recent call last):
  File "/Applications/Zenmap.app/Contents/MacOS/zenmap_wrapper.py", line
266, in <module>
    substitute_key_file(in_file_name, out_file_name, REPLACEMENTS)
  File "/Applications/Zenmap.app/Contents/MacOS/zenmap_wrapper.py", line 60,
in substitute_key_file
    out_file = open(out_file_name, "w")
IOError: [Errno 13] Permission denied:
'/Users/nilsonj/.zenmap-etc/pango/pangorc'

valentina:~ nilsonj$ ls -la ~
drwxr-xr-x   8 root     staff     272 Nov  9 16:42 .zenmap
drwxr-xr-x   4 root     staff     136 Nov  9 16:40 .zenmap-etc

Should these folders be hosed and permissioned as user?  ie, does first run
need to occur as a regular user to ensure permissions are correct?

valentina:~ nilsonj$ sudo rm -r ~/.zenmap-etc ~/.fontconfig
rm: /Users/nilsonj/.fontconfig: No such file or directory

valentina:~ nilsonj$
/Applications/Zenmap.app/Contents/MacOS/zenmap_wrapper.py
Xlib:  extension "RANDR" missing on display "/tmp/launch-ZdeUX0/:0".
/Applications/Zenmap.app/Contents/Resources/lib/python2.5/site-packages.zip/zenmapGUI/App.py:158:
GtkWarning: gdk_x11_atom_to_xatom_for_display: assertion `atom != GDK_NONE'
failed

... which loads a GUI just fine and does not crash with a pango error.
(However it does complain about root permissions being absent from the
current session.) ... now running as root again ....

valentina:~ nilsonj$ sudo
/Applications/Zenmap.app/Contents/MacOS/zenmap_wrapper.py
Xlib:  extension "RANDR" missing on display "/tmp/launch-ZdeUX0/:0".

Success and less a GTK assertion error ...

valentina:~ nilsonj$ ls -la ~
drwxr-xr-x   8 root     staff     272 Nov  9 16:42 .zenmap
drwxr-xr-x   4 nilsonj  staff     136 Nov  9 16:48 .zenmap-etc

... still some self-awareness problems creating resource files, IMHO.  How
should these be permissioned idealistically?
