http://bugs.winehq.org/show_bug.cgi?id=27340

Summary: WoW Launcher crashes, NULL pointer dereferenced
           Product: Wine
           Version: 1.3.21
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: mshtml
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

This bug started happening at about the same time as the 1.3.21 release. What
is happening is that the get_script_guid() function in dlls/mshtml/script.c is
being passed nsscript=NULL. This function contains the line:

nsres = nsIDOMHTMLScriptElement_GetType(nsscript, &val_str);

where nsIDOMHTMLScriptElement_GetType() is really a macro defined as:

#define nsIDOMHTMLScriptElement_GetType(This,aType)
(This)->lpVtbl->GetType(This,aType)

So being passed NULL for This is a "Bad Thing", obviously.

I have no idea *why* nsscript is NULL suddenly; presumably doc_insert_script()
is being passed NULL.
