FIX: PotreeConverter/PotreeConverter/src/main.cpp
     check: https://github.com/potree/PotreeConverter/issues/265

     "Hi,
	I'm using Ubuntu 16.04. Had the same issue with segmentation fault.
	In the main.cpp file line 72 you'll find: args.addArgument("source,i,", "input files");
	remove the extra comma so it looks like this: args.addArgument("source,i", "input files");
	This ended the segmentation fault issues for me.
	Thanks"
