Interactive simulator python script raises error

I noticed that when running a Python script from a Space Creator window I get an import error:

While calling the same Python script from a console just works fine

This Python script is called by src/libs/libiveditor/modelchecking/modelcheckingwindow.cpp by calling make simu in a xterm window:

Note
Check to use

$ export XDG_DATA_HOME="$HOME/.local/share:/root/.local/share:/usr/local/share/:/usr/share/"
$ export XDG_DATA_DIRS="$HOME/.local/share:/root/.local/share:/usr/local/share/:/usr/share/"

Which is neede to be called before SpaceCreator in some scripts.
