Log of the crash
Recently, I've been noticing that X crashes on start-up when I have a monitor configured on VGA_1 but it is not connected. If I comment out the configuration line or connect the monitor, X starts just fine.
I'm not sure when this first started happening, as I have not been using a multi-monitor setup recently. Sorry I can't be more help in that regard.
I'm using git master (commit f1c6cc86), X Server 184.108.40.2066 (1.5.0 RC 6), on Gentoo Linux
Matthew: Please also provide your config file.

xorg.conf for X Server 1.5.0
This is a bug in the XRandR 1.2 code in the Xserver.
I cannot reproduce this bug any more with the current GIT head of the xorg/xserver package. Therefore I assume it's fixed.
