It's failing on testtk, which makes sense, because it's running as a background twisted process, and thus can't access the window server. It doesn't really make sense. It should skip the test, instead of failing it. I.e. aborting the Python process is definitely not a good response. Yes, you're right. It's a bug in the test. No, I'd say it's even deeper, in the Tcl integration. There shouldn't be a way to cause an interpreter abort, except by calling os.abort().

This is a bug in Tk:

root = Tkinter.Tk() Thu May 13 20:45:13 Rivendell.local python[84887] : kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged. _RegisterApplication(), FAILED TO establish the default connection to the WindowServer, _CGSDefaultConnection() is NULL. 2010-05-13 20:45:16.751 Python[84887:d07] An uncaught exception was raised 2010-05-13 20:45:16.762 Python[84887:d07] Error (1002) creating CGSWindow 2010-05-13 20:45:16.955 Python[84887:d07] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Error (1002) creating CGSWindow' *** Call stack at first throw: ( 0 CoreFoundation 0x00007fff85e31d24 __exceptionPreprocess + 180 1 libobjc.A.dylib 0x00007fff860000f3 objc_exception_throw + 45 2 CoreFoundation 0x00007fff85e31b47 +[NSException raise:format:arguments:] + 103 3 CoreFoundation 0x00007fff85e31ad4 +[NSException raise:format:] + 148 4 AppKit 0x00007fff84614aba _NSCreateWindowWithOpaqueShape2 + 473 5 AppKit 0x00007fff845a9055 -[NSWindow _commonAwake] + 1214 6 AppKit 0x00007fff845c6d3d -[NSWindow _makeKeyRegardlessOfVisibility] + 96 7 AppKit 0x00007fff845c6cb2 -[NSWindow makeKeyAndOrderFront:] + 24 8 Tk 0x000000010075b86c XMapWindow + 155 9 Tk 0x00000001006ca6d0 Tk_MapWindow + 89 10 Tk 0x00000001006d35e6 TkToplevelWindowForCommand + 2658 11 Tcl 0x00000001006300d3 TclServiceIdle + 76 12 Tcl 0x00000001006162ce Tcl_DoOneEvent + 329 13 _tkinter.so 0x0000000100595683 Tkapp_CallDeallocArgs + 277 14 readline.so 0x00000001001f1f9a initreadline + 1280 15 Python 0x00000001000076a1 PyOS_Readline + 239 16 Python 0x0000000100008a57 PyTokenizer_FromString + 1322 17 Python 0x00000001000090a0 PyTokenizer_Get + 154 18 Python 0x0000000100005698 PyParser_AddToken + 1018 19 Python 0x00000001000a2320 PyParser_ASTFromFile + 146 20 Python 0x00000001000a443f PyRun_InteractiveOneFlags + 345 21 Python 0x00000001000a4615 PyRun_InteractiveLoopFlags + 206 22 Python 0x00000001000a4685 PyRun_AnyFileExFlags + 76 23 Python 0x00000001000b0286 Py_Main + 2718 24 Python 0x0000000100000e6c start + 52 25 ??? 0x0000000000000001 0x0 + 1 ) terminate called after throwing an instance of 'NSException' Abort trap

This is running /usr/bin/python in a session as a user that doesn't have access to the GUI. The text above says that there is an uncaught ObjC exception, caused by the lack of a connection to the window server. Tk should have converted that to its own style of errors but didn't.

Bill: could you please file an issue for this in the python tracker, it should be possible to add a workaround for this to the Tkinter extension.
