Comment 3 for bug 912855

I just got this same problem. After clicking the "Be the first to review it" link for Phlipple in the Ubuntu Software Center, the "Review Phlipple" window came up, saying "Signing in...". A few seconds later, this crash came up, and it stayed stuck there.

Clicking Cancel and trying again leads to same exact crash again, so this is very reproducible for me.
