www/chromium crashing whole system

hi there,

i'm having an issue with www/chromium. sometimes it will completely lock up my
system without producing a core dump. i'm running HEAD (r215102; amd64).

this time however chrome.core made it to disk somehow:

Core was generated by `chrome'.
Program terminated with signal 11, Segmentation fault.
