No targets were specified error

[Jesper Kückelhahn <dev.kyckel () gmail com>]

Hi list,

After updating to an svn revision after 30538 I'm getting some strange errors, that might to be related to the input 
arguments to nmap. If I attempt to execute a basic nmap scan, I get a warning that no targets were specified.

"
$ nmap 192.168.1.20

Starting Nmap 6.26SVN ( http://nmap.org ) at 2013-01-24 00:35 CET
WARNING: No targets were specified, so 0 hosts scanned.
Nmap done: 0 IP addresses (0 hosts up) scanned in 0.06 seconds 
"



If I add a single debugging flag I get the same error, but if I add two i get:

"

Adding an extra debugging flag gives:
