The test started passing after r259709, which updated test expectations after r259705. However, the test is still crashing occasionally. For instance, it crashed in GTK test build #13279 (https://build.webkit.org/builders/GTK%20Linux%2064-bit%20Release%20%28Tests%29/builds/13279). Step "MasterShellCommand -> View LayoutTest results" should include a stacktrace, but the test is not reported as crash there. Inspecting LayoutTest stdio shows: 07:34:04.006 127258 worker/11 inspector/console/webcore-logging.html crashed, (stderr lines): 07:34:04.006 127258 Error sending IPC message: Connection reset by peer 07:34:04.006 127258 Error sending IPC message: Broken pipe 07:34:04.006 127258 Error sending IPC message: Broken pipe 07:34:04.006 127258 Error sending IPC message: Broken pipe 07:34:04.006 127258 failed to create drawable 07:34:04.006 127258 Xlib: sequence lost (0x100f1 > 0xf5) in reply type 0x0! 07:34:04.006 127258 07:34:04.006 127258 (WebKitWebProcess:34584): Gdk-ERROR **: 07:33:58.050: The program 'WebKitWebProcess' received an X Window System error. 07:34:04.006 127258 This probably reflects a bug in the program. 07:34:04.006 127258 The error was 'BadMatch (invalid parameter attributes)'. 07:34:04.006 127258 (Details: serial 241 error_code 8 request_code 148 (GLX) minor_code 34) 07:34:04.006 127258 (Note to programmers: normally, X errors are reported asynchronously; 07:34:04.006 127258 that is, you will receive the error a while after causing it. 07:34:04.006 127258 To debug your program, run it with the GDK_SYNCHRONIZE environment 07:34:04.006 127258 variable to change this behavior.

This test, or group of tests, has been passing for the last 4000 revisions. Closing bug. Gardened in r278519.
