It is a known bug that got pushed with v32. I have not seen anything about fixing it yet though.
It happens with any model window (which includes devtools) or when Chrome is running in app mode.
Chrome isn’t actually crashing and you can still continue to use it, but that will continually pop up with devtools open.
The issue has been fixed as of today’s (1/28/2014) update. Version: 32.0.1700.102 m
