unity-2d-panel crashed with SIGSEGV in malloc() on unity-2d logout

[manny]

logged out from unity 2d and logged into unity 3d. After a few minutes i got a screen saying that unity 2d crashed... but i was already logged out ...

was unity 2d still running in the background, even when you log out and log into unity 3d?
