Same issue with a fresh python 3.3.5:

361         if (PyObject_IS_GC(op)) {
(gdb) backtrace 
#0  visit_decref (op=0xb00000000, data=data at entry=0x0) at Modules/gcmodule.c:361
#1  0x000000000052d9da in BaseException_traverse (self=0x7ffff156d328, visit=0x4c0800 <visit_decref>, arg=0x0) at Objects/exceptions.c:100

Is it a python bug, or could it be an issue with the cx_oracle extension ?
