I have pinned tabs. and sometimes I accidently click next to the first tab instead of hitting the tab and if its done three times rapidly chrome just shuts down as If you hit the X on the other side to shut down chrome.  which stinks because it closes all my tabs.  not sure if thats an expected thing to happen and I should just be more careful or a bug.
