safari keeps crashing

Hi there

Running Tiger (10.4.11) and the version of Safari I'm running (4.1.3) - the latest for Tiger - keeps crashing and quitting - has been working well since forever, why should it suddenly stop working?

Have tried to remove Safari and re-install - nothing changes, still keeps crashing...

Any thoughts / answers or suggestions welcome...

Thanks
