There is something weird going on with our section counters.
When lyx crashes and leaves emergency file behind, in the next
lyx run I choose for loading original and removing emergency file.
The 'original' file is loaded but all counters are wrong, starting
higher than they should ('5' in this case).
That's why my recipy says 7.2 although with clean file, it should state 3.2....
