Programs that i tested that Crash Unity 3D:
-Idle2
-Idle3
-NameBench
-Skencil
-PasswordGorilla
-Snackamp
-the Imagemagick GUI
-All my open source programs
-and a lot more i forgive right now...

Too bad, im a TKinter developer and all my apps dont work now, but is not a fail of my code,
but something with Unity 3D, even the Idle IDE from official repos crash the Unity 3D.

Global Menus dont work with other than GTK/QT based apps, so dont work on TK apps.
