           Summary: Missing NULL check for vendor string from
                    glGetString(GL_VENDOR)
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Platform

glGetString(GL_VENDOR) is possible to return NULL value but in Webkit we are not validating the return value before we call strstr() to compare the vendor list. Hence webkit crashes when it does not get vendor string response from openGL call glGetString(GL_VENDOR).

Refer to http://www.opengl.org/sdk/docs/man/xhtml/glGetString.xml for glGetString() description.
