you can only access python from 1 thread at a time. I have not done any messing around with python types so I do not know if those require the gil but from what you said it seems like they may. In order to work with python from multiple threads you need to manage the gil in your app. Just do a search on this list for gil and you will get all the information you need. In the C api, I think the functions to look into are PyGILState_Ensure and PyGILState_Release.
