No, I'm facing similar behavior with the gtk3 version (calling a python
function, and then opening the python console does not work properly). I
am not a Python expert (actually, I don't know Python at all). This
makes things difficult to analyze and fix. Just the fact that this also
occurs with 1.10 makes me think I might not have introduced a new bug)
