Gah, this appears to be related to my change that made some file names
Unicode strings instead of plain byte strings. That was an attempt to
fix the bug in http://seclists.org/nmap-dev/2008/q3/0482.html.

jah reported a similar crash in http://seclists.org/nmap-dev/2008/q3/0497.html.
I thought we had it fixed in http://seclists.org/nmap-dev/2008/q3/0537.html.

Please try r10003. That coerces a Unicode string to a plain byte string
in an instance we thought was unnecessary before.

(By the way if anyone wonders what the distinction is between a Unicode
string and a plain byte string, there's a good page on Unicode in Python
at http://kofoto.rosdahl.net/wiki/UnicodeInPython.)
