I don't know why the CQ fails to catch this, but I've been consistently getting this error for the last two days.  I have setup a new board, repo synced and still get it.  I've run repo status and everything looks good.  To reproduce:

repo sync -j8
(enter chroot)
emerge-{BOARD} autotest-chrome

You should get this error:
