4.3.6 crash when installing Win8.1 guest

[xerces8]

My host is Windows 8.1 Pro 64 bit.

I had vbox 4.3.4 and just updated it to 4.3.6.
I tried to install the Windows 8.1 trial to it, but a few seconds after booting the ISO I got a guru meditation.
As recommended by the dialog, I attach the PNG and log (zipped due to forum size restriction) files.

The iso image I used was 9600.16384.WINBLUE_RTM.130821-1623_X64FRE_ENTERPRISE_EVAL_EN-US-IRM_CENA_X64FREE_EN-US_DV5.ISO

PS: The same thing worked fine with 4.3.4. Is there a simple way to downgrade?

Post the guests log file ( as an attachment )

[xerces8]

Is that a different log than the one I attached?
Where is it, what filename?

Change the guest OS type in the VM config to Windows 8.1 64 bits.
