I was connected to my linux box for several hours and was booted for no apparent reason.  After reconnecting I checked my host log and found this snippet:

chrome-remote-desktop-host: ../../third_party/libvpx/source/libvpx/vp8/common/treecoder.c:92: void vp8_tree_probs_from_distribution(int, vp8_token *, const vp8_tree_index *, vp8_prob *, unsigned int (*)[2], const unsigned int *, unsigned int, int): Assertion `tot < (1 << 24)' failed.

It looks like an assertion failed in the vp8 code which causes the host to crash.  IIRC this is not a released host version and is not a common problem but wanted to log it in case it is interesting later.
