An example of WebContent crashing

The WebContent process seems to crash occasionally if I "inspect element" a playing video. From the crash log it seems like there's a null pointer dereference near the top of WebCore::buildObjectForKeyframes, but I didn't look into it too much. I know this didn't use to crash before, so I'm guessing it has something to do with all the new code in this area.

I believe this was fixed in r259205 (bug 209682).

Sounds like it. I'll let you know if I see this in the next Safari Technology Preview release.
