Bug with sharing Safari link via e-mail. iPhone

When attempting to share a link via email from Safari I am unable to browse to my contact groups. I can see whatever group I happened to last browse to when sending an email but when I hit the back arrow from the contacts window to see all groups it gives me no options...just a blank screen.
This is with an 32GB AT&T iPhone 4 running iOS 4.3. I also use MobileMe to sync my contacts/groups if that helps.
