Chromium does not use NSS database for CAs or client certificates

Binary package hint: chromium-browser

Under Ubuntu 10.04, I was able to install a CA (http://ca.mit.edu/mitca.crt) and a client certificate ("me.p12") and use them, following the instructions at http://code.google.com/p/chromium/wiki/LinuxCertManagement . The commands were:
$ certutil -d sql:$HOME/.pki/nssdb -A -t "C,," -n MIT -i mitca.crt
$ pk12util -d sql:$HOME/.pki/nssdb -i me.p12

In Maverick, I am able to install the CA and certificate, but I can no longer use them to make secure connections. For example, in visiting https://web.mit.edu/consult/www/certificate/test.html I see an error message:
Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error.

I notice that this error is the same *whether or not* the directory $HOME/.pki/nssdb exists. To me, this indicates that even when the keys are present in the database, Chromium is unable to access them properly.
