OK, how about r207?

What triggered the crash that I fixed there was your call 
"pipmak.overlaynode(2)" in main.lua, at a time when there's no 
background node yet.

That was fortunate insofar as it pointed us to this bug, but otherwise 
doing such things in main.lua is a bad idea. You shouldn't assume that 
main.lua is run exactly once when the project is opened. That's 
currently the case, but it may change in the future. Initialization 
procedures belong in onopenproject(). In a way, main.lua should be 
treated as a data file, not as a program, and running it should have no 
side effects.

Apart from that, overlaying a node when there's no background node yet 
doesn't make much sense to me, but as it happens to work the way you 
want (the real background node is later inserted under it), modulo 
undiscovered bugs, I decided to keep it allowed for the time being. But 
for my taste, the proper place for that would be onenternode() of the 
main node.

I'm still uncertain about the cause of the random reproducibility of the 
crash, there might be another bug lurking there. Will investigate further.
