The following crash happens from time to time when resizing google-chrome displaying a flash-based website. I should add that chrome behaves quite strange as soon as it loads flash-based content since a few days (not sure whether a chrome-update or updated mesa caused this).

All components are from Fedora-19-Beta updates-testing repository, except for the intel-driver which is: 2.21.9-4-g7e1e18a
