The log files do not indicate any crash. You do have several plugins, any on of which could be causing a problem...propwash specifically as it was the last thing that was running. Also, it would be helpful to know what you were doing specifically when you were "tinkering around".
If you want to help diagnose the problem you should remove all your plugins and then re-test the Saab. If everything is OK then start putting the plugins back in one-at-a-time. If you get a crash after one of theplugin re-installs, that plugin is probably the problem.
