ctkahp quit unexpectedly
Had the same problem in an environment that uses Active Directory. When I attempted to run Chrome, I would get the error. The error mentioned the CryptoTokenKit, or something like that.

Oddly enough, other accounts on the same machine worked fine.

When I dug deeper, I found that the client did NOT have a Mobile Me account. Setting them up with a Mobile Me account appears to have solved the problem.
