Steps to reproduce:
1. If WebKit has crashed, click OK to send away the report
2. Click WebKit icon on the Dock to launch it
3. Program launches but remains loading the start page. Changing location bar to load any other page doesn't work either, stalls on loading.
It should be functional again once the report has been sent and Safari restarted.
Console log reveals:
27.02.10 11:17:01 Safari WebKit failed to shut down cleanly. Checking for Safari extensions.
27.02.10 11:17:01 Safari WebKit r55270 initialized.
Workaround: close Safari and restart it once more.
The issue still persists in r60332. Safari just crashed over Debug Flash Player and it didn't load any pages after coming up again. Had to make another restart.
Issue still there in Safari version 5.0 (6533.16, r63285).
How long are you waiting for the page to load after a crash?
