Virtualbox crashes Os X host

[Aanund]

I run a vm with Windows 7 guest on a Os X host, VM running maximized (not fullscreen) on separate monitor. Sometimes (almost once a day) when moving between vm and host (for instance checking mail or browser on host) computer will crash hard (entire computer).

Cannot guarantee that this is a virtualbox problem, but virtualbox is the last thread in panic dump from os x.

Problem has existed entire 4.2 version (also present in 4.2.10).

Happened again (second time today, attaching logs).

Please reopen if still relevant with VBox 4.3.2.
