Suddenly, this crash starts happening for me too. It didn't last night, but it 
does now. It happens when I run "install" from the AM. At the end of the 
install it seems we trigger a parse and crash.

_jd is, as expected, 0. Checking for it is easy enough, but the fact that this 
happens suggests an error elsewhere..
