One of our LibreOffice developers attempted to create a minimal 
reproducer, without success so far. He said he has run into the same 
failure even before 3.5.0, so it is somehow intermittent. I know it's a 
big ask to try with our full build, but if anyone is interested, we can 
provide support with any issues with the initial setup.
