[Bug 319656] Re: nmap script engine error

[Jay Zeng]

I haven't try the diff yet, but the (current) package is obvious broken
I am running ubuntu jaunty (9.0.4), with nmap version (downloaded from
the ubuntu repo) :

/usr/bin/nmap -v

Starting Nmap 4.76 ( http://nmap.org ) at 2009-07-14 22:29 PDT
Read data files from: /usr/share/nmap

I also tried to download source from svn (version 4.90RC2, svn r12639) and made a new build, another (similar) error message appears:
