Well done!

I've just worked through your notes on my OSGeo4w master - 3700d84 (unfortunately not a fresh install, might try later) and actually had crashes where you did. 

I did not get any blank PDFs though. 

Where your vector exports about twice as big as the raster versions?
Is that expected?
