virtualbox-ose-4.2.18_1
tightvnc-1.3.10_3

>Description:
	If I configure a VBox client to use VNC with simple authentication
	then connecting to it from a VNC viewer causes it to die with SIGBUS.

	This doesn't occur if I don't configure authentication (though my
	VNC client still asks for a password and VBox always rejects the
	connection).

	This is a regression from VBox 4.1 - which didn't request
	authentication if it wasn't configured.

>How-To-Repeat:

	VBoxManage setproperty vrdeauthlibrary "VBoxAuthSimple"
	VBoxManage modifyvm FreeBSD_64-10  --vrde on --vrdeextpack VNC --vrdeaddress 192.168.123.200 --vrdeport 6213  --vrdeauthtype external
	VBoxManage setextradata FreeBSD-10 "VBoxAuthSimple/users/peter" $(VBoxManage internalcommands passwordhash MyVncPassword | sed 's/^.* //')
	VBoxHeadless -s FreeBSD_64-10
