ssh-agent spawns multiple times via Xsession

In /etc/X11/Xsession.d there are two files

90xorg-common_ssh-agent

and

90x11-common_ssh-agent

If ssh-agent is enabled in /etc/X11/Xsession.options, having both of these files appears to 'stack up' the $STARTUP to spawn ssh-agent twice , starting the window manager defined in the '.desktop' files twice.

By commenting out 90x11-common_ssh-agent this stopped this issue.

To reproduce this issue as an example, install fluxbox and run it as a session from gdm. Check ps and you'll see probably 4 instances of startfluxbox running.
