French Civil War in 1899

Supposing the French government descends into civil war in early 1899 (Dreyfus troubles, leader dies from strange activity while lady involved denies intention, Orleanists and Bonapartists are active, etc.), what becomes of France and how is the rest of Europe and the world affected?
 
This is the wrong period for civil war. By the nineties, France was stabilizing. I think a failed coup by, say, Boulanger in the 1880s may work to cause a civil war.
