Wasn't anything else in the system logs, I did look, but this happens
entirely in userspace.  It does not happen on my system that uses a
NVIDIA G86 Quadro NVS 290, but that also only drives a single monitor
with no rotation.

I ran into this too. Worked with 1.20.6, fails with 1.20.7.
It is likely related to nouveau.

I wonder whether the problem could be related to the nouveau driver.
I've had lots a problems (crashes...) with it, on a machine I do not
use very much. The last one a few weeks ago:

Nope, vanilla amd64 package from the repo, not a rebuild.

Hello Jamie Heilman,
I just tried to retrieve some line information from the backtrace.
Unfortunately I could not match the addresses with the
binary from the debian repository.
Was this backtrace by any chance built with a local
rebuild of the xserver-xorg-core package?

Kind regards,
Bernhard
