http://trac.webkit.org/changeset/86870 Note: This is with the patch at https://bugs.webkit.org/show_bug.cgi?id=60722 applied. I haven't confirmed if it crashes without it yet. $ WebKitBuild/plugindocument-new/Release/bin/DumpRenderTree -v http://127.0.0.1:8000/plugins/plugin-document-has-focus.html 127.0.0.1 - - [24/May/2011:18:52:19 +0100] "GET /plugins/plugin-document-has-focus.html HTTP/1.1" 200 457 127.0.0.1 - - [24/May/2011:18:52:19 +0100] "GET /plugins/resources/plugin-document-has-focus.pl HTTP/1.1" 200 3 The program '<unknown>' received an X Window System error. This probably reflects a bug in the program. The error was 'BadValue (integer parameter out of range for operation)'. (Details: serial 236 error_code 2 request_code 53 minor_code 0) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) This isn't reproducable in QtTestBrowser so must be specific to DRT.
It doesn't happen in trunk - the test just times out. So likely a product of something happening in the patch at bug 60722.
