This is exactly what Issue8716 was about. The buildbot has no way of knowing ahead of time whether a test will cause a crash or not. Yes, Tk should not crash but it does in some cases. Speaking of #8716, that reminds me that there is an open issue with it (documented in Issue17496). There is the start of a patch there to use a more general approach to testing for a working Tk that might be applicable on all platforms.

Issue17496 contains a patch that might fix the crashing problem for OSX (and possibly other Unix-y platforms). I haven't been able to test this in an environment that's simular enough to the buildbots (that is, a system where the user running the test does not have GUI access).

That patch starts wish (the TCL shell) in a subprocess, and skips tests when that doesn't work (on OSX that would be because Tk crashed).
