I find that Trusteer's Rapport security software always has problems with chrome when chrome gets updates.
It's software that my bank pesters me to install whenever I try to log in to my account.

Recently when chrome updated to version 6 it would crash constantly. As soon as I started chrome it would crash.

I uninstalled Rapport and now chrome works normally.

If anyone has Rapport installed and is having trouble with Chrome then you should try uninstalling Rapport.
