Re: zenmap crashes in OSX 10.6

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
override rw-r--r--  root/staff for
/Users/nilsonj/.zenmap-etc/gtk-2.0/gtk.immodules? y
rm: /Users/nilsonj/.zenmap-etc/gtk-2.0/gtk.immodules: Permission denied

rm: /Users/nilsonj/.zenmap-etc/pango: Permission denied
override rwxr-xr-x  root/staff for /Users/nilsonj/.zenmap-etc? y
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?
