Seems to have started after https://trac.webkit.org/changeset/211457 See the WebKitTestRunnerApp crashes here: https://build.webkit.org/results/Apple%20iOS%2010%20Simulator%20Release%20WK2%20(Tests)/r211467%20(3340)/results.html
That is definitely https://trac.webkit.org/changeset/211457. If you look at what that change is doing, it attempts to launch an app to check that the app is installed. These crashes can be ignored, they're real, but they don't matter. I didn't really think about them. I'll put up a fix shortly that should get rid of them.
