            Bug ID: 156311
           Summary: [GTK] gdk_x_error() and WebKitWebProcess crash
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
          Assignee: webkit-unassigned at lists.webkit.org

Steps to reproduce:
1. Launch minibrowser
2. Load https://blogs.gnome.org/mcatanzaro/

Expected results: WebKitWebProcess would not crash

Actual results: WebKitWebProcess crashes (for me) 100% of the time:

(WebKitWebProcess:19243): Gdk-ERROR **: The program 'WebKitWebProcess' 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 177 error_code 2 request_code 154 (GLX) minor_code 24)
  (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 GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

Environment: Fedora 23, GNOME 3.18.x, X11, unmodified WebKitGtk+ jhbuild environment (including jhbuild-built dependencies).

I've attached a backtrace from debug build after doing what the error suggested.
