Comment 10 for bug 367354

When attempting to do the security updates yesterday (Jan 8, 2010), I am now experiencing this error. I tried purging xulrunner-1.9.1, then getting back the packages I need (using update manager to get desktop-couch back and apt-get install firefox to get the rest back, but I'm still getting the same errors.)

This is pretty annoying because I am unable to use Firefox on Ubuntu now.
