           Summary: [bisected glx]: assert triggered by kwin, when
                    glxCreateWindow is called with NULL attrib_list
           Product: Mesa
           Version: git
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: GLX
        AssignedTo: mes...@li...
        ReportedBy: Mag...@gm...


KDE's kwin calls glxCreateWindow with NULL as the attrib_list parameter when it
sets up OpenGL based compositing. Since Mesa commit
706fffbff59be0dc884e1938f1bdf731af1efa3e this triggers an assert in
CreateDrawable (glx_pbuffer.c:382), and the application crashes.

The man page for glxCreateWindow states explicitly that NULL is allowed to be
passed as a value to the attrib_list parameter
(http://www.opengl.org/sdk/docs/man/xhtml/glXCreateWindow.xml).
