Could you check if the crash is caused by touchpad multitouch gestures or by alt+tab too?
I don't think it is being caused by multitouch trackpad gestures. TWin is the window manager from Trinity Desktop, a fork of KDE3 3.5 and it doesn't support trackpad gestures for that, or if it does, I don't use it. I used keyboard shortcuts to change to another virtual desktop there. So yeah, can confirm it happens without gestures. I don't know if it has anything to do with how the window is in another state when in a different virtual desktop but if it is in the same, doesn't happen.
