    ** Emacs crashes with SIGTRAP when trying to start a WebKit xwidget.

    This could happen if the version of WebKitGTK installed on your system
    is buggy, and errors out trying to start a subprocess through
    Bubblewrap sandboxing. [snip]

I wonder: Besides running into SIGTRAP, how do you know if you might
have a buggy version?  Does this happen on only old versions, or only on
new ones?

Would it make sense to add a brief note about that?  Just an idea.

(Please ignore if this is irrelevant, I haven't really been following
the xwidget work.)
