 I notice that the file is being created with zero-length on my
system, so the program must be getting into QgsProject:write and
crashing there. There's a method for write() with a QFileInfo arg as
well as the method with no args. Not sure if this is a problem, but I
thought that kind of thing is handled by the SIP wrappers.

 I tried creating a QFileInfo object in python and calling :write but
it still crashed, something like:

 f = QFileInfo("/tmp/foo.qgs")
 p = QgsProject.instance()
 p.write(f)
*crash*

I need to set up a Qgis build environment to get any further with this...
