Q: Safari kernel panics
I have a 2008 MacPro that typically runs very stable - rarely have crashes/restarts
A couple of months ago, I began having kernel panics with Safari - I made no changes to my Mac at that time. I could launch Safari and use it it briefly (minute or so), then my Mac would lockup and restart. I tired deleting some Safari files (like cache/cookies/plist) and also tried re-installing the OS (10.11.5) with no luck - so I switched to Chrome.
For the past couple of months, I've been using Chrome with no further kernel panics - so I gave up on Safari.
With the latest OS update, I saw there was a new version of Safari installed, so I updated to OS 10.11.6, relaunched Safari, and the kernel panic returned. I continue to use Chrome without problems.
I've included the last Panic Report in the hope that someone here can point me in the right direction of solving this problem:

Thanks! Or maybe I'll just wait to Sierra... ;-)
