I installed last 0.40b version and start a new game. I will check all leaders, etc. Combination of leaders - maybe could be the reason of crash. However, I don't think that the directory name somehow could affect on the crash during saved game loading. As far as I know any information about directory name in absent in game codes (source codes, phyton and xml files). Such information appears only in save file. As result you can load the save file only on the game version where this file was created.
