I'm also having zenmap crashing on 10.5.1, but in a different way. I
maintain the nmap package for Fink and have an experimental 4.23RC3

This is the error:

HOOK:

It seems that 'page' is missing the len() function? I'm not very
familiar with python.

Hmm, I don't know. What version of PyGTK are you using?
ScanHostDetailsPage is a subclass of gtk.Expanderm, which for me has a
length (len(page) -> 2 in this case). len() is implemented as a method
called __len__, which in PyGTK 2.10.4 is inherited by gtk.Expander from
gtk.Container.

But I think the code is mistaken anyway. It looks more like
switch_host_details is able to take either a single page or a list of
pages. The code that says "if type(page) == type([])" is testing if page
is a list. I think that

    elif len(page) == 1:

is trying to see if page is a list containing more than one page, but it
also will be true if page is a gtk.Expander containing a single element.
Can you try the attached patch?

With this patch, zenmap works. Thanks! I think my problem was that my 
PyGTK is old: 2.6.6. Fink is in the process of upgrading to the latest 
GTK, but because of the dependency on cairo it has been necessary to 
update hundreds of packages simultaneously with new dependencies and 
it's taking a lot of time. :/

Hmm-- I don't show a PyGTK in MacPorts; does Fink work happily alongside?
