13991	NUL character with a value of 0 ^@ Shown In Linux Console	VBoxGrl		"Hi,

My Specs;

Slackware 14.1 x86_64 - Host
screen size 1920x1080
Virtualbox 4.3.24 - (compiled from source)


Slackware 14.1 x86_64 - Guest
screen size 1920x965
Virtualbox 4.3.24 - (Guest Additions installed)

I noticed when I restart or shutdown Slackware, in the console, I am seeing the NUL character with a value of 0 that is represented as `^@` appear next to text on the screen.

I thought at first something in the Slackware system was causing this.

I was running the Guest with the default of 'Auto-resize Guest Display', this causes the console to have a small size, and it seems for some reason Virtualbox doesn't like it and creates the Nul Character, because if I change the Guest to 'Scaled Mode' it never appears.

I tested this several times changing back and forth with the 'Auto-resize Guest Dispaly' and 'Scaled Mode', and everytime it was on 'Auto-resize Guest Display' it appeared, and everytime it was on 'Scaled Mode' it did not appear.

I'm attaching a screen shot, called vb_character.jpg, notice the line with the red dot I marked, to the far left the word; `^@Sending`..."	defect	new	other	VirtualBox 4.3.24				Linux	Linux
