Comment 5 for bug 1288115

This bug is still persistent, it seems to be related to particular packages that are installed as dependencies with other apps, I read somewhere that it was pycrust, what I've experienced is that lxsession-default-apps settings are ignored and everything located in /etc/xdg/autostart is loaded regardless of what is and isn't selected in lxsession-default-apps. The latest updates, at least for me, brought this bug out, for me it didn't exist until the updates.
