mod_wsgi (pid=88536): Unable to change working directory

Hi,

I'm seeing this error in my main Apache log when I switched to using 
daemon mode:

[Tue Jan 12 21:13:47 2010] [alert] (2)No such file or directory: 
mod_wsgi (pid=88536): Unable to change working directory to '/nonexistent'.

Not sure why it would be happening though, why mod_wsgi would need to 
change directories, or what the "correct" solution is? If someone could 
please point me in the right direction, it would be greatly appreciated.

Thanks,
mog
