Status in KaliVeda data analysis framework:
  New
Status in KaliVeda 1.8 series:
  Fix Committed

Bug description:
  J'utilise KVSimDirGUI pour analyser des simulations BLOB. Version KV1.8.10 à l'IPN
  Pour tester, je veux réduire le nb evenements : je décoche la case "all" 
  et j'incrémente jusqu'au nb choisi. Si ce nombre est >=10, tout va bien. Dans le cas contraire ça plante :
