@skione no special requirements for windows. What is troubling is that it is hapenning only for one user. One thing I can think of would be some hardware issue (for example OpenPGP.js using GPU features for some crypto operations) and that this user particular setup causes chrome to crash. That could be some hardware/software integration bug.
We have seen this kind of issues before on some Apple computer with a given version of a graphic card, where the quickaccess would freeze (but not crash). We have also seen OpenPGP.js crypto code crashing chrome before (that was a chrome bug).
Could you tell us more about the hardware? Could you check if other users with exactly same hardware are having similar issue (to rule this out?).
Generally speaking, the browser crashing is a browser bug btw, that might be useful to report this to chrome tracking system, as this may have security implications.
