Hello Keith,
I suffer from the same problem - crash on startup.
The backtrace is identical (attaching).
The circumstances are the same - I have four monitors with two nvidia cards
using nouveau driver.
I am using xinerama.

After applying your patch the backtrace is different:

double free or corruption (!prev)
