After using the new profile for a few minutes, it appears the problem was not due to my previous profile. The crash is caused when visiting certain websites (GMail among them, for example). As I had GMail open in a tab when I started Firefox, this caused the crash on start-up. Creating a completely new profile, starting Firefox with that profile, and visiting GMail causes the same crash and same errors as before. An Apport report for this crash (ie. with a totally blank profile) can be provided if that helps.
