For people that are crashing in Quick Time do you continue to have trouble if you turn off the webkit Quick Time plug-in? You'll still have the regular NS plug-in loaded so Quick Time should still load.

Open up your plug-in preference pane.
Find "QuickTime Plugin.webplugin" and restart OmniWeb.
Do you continue to crash?

If you re-enable the plug-in above and disable "QuickTime Plugin.plugin" do you start crashing again after a restart?

You can also perform this test by setting aside the appropriate plug-in file found in:

/Library/Internet PlugIns/

While OmniWeb is not running.
