If I remember correctly you are a Mac user to, aren't you? Are you using 10.6.7 too with Python 2.6.1 ? May I try to recompile pythonocc with OCE? Can it fix this error? This bug is incredibly hard to track down since the python debugger does not stop when the C++ code crashes... Do you use any special tools to debug such errors when developing pythonocc?
