Looks like it's trying to get strlen(NULL) and that's coming from trying to find an invalid GType, sourced 
from Python, possibly an enum based on frame 4. One can't tell from this what it is, of course. Maybe you run 
your program under the python debugger and figure out what is the terminal python call and work from there.
