[bug #26046] Infinite loop on quit...

[Gregory John Casamento]

Follow-up Comment #1, bug #26046 (project gnustep):

 
I've narrowed it down to this code in XGServerEvent.m @ line 942

 28036        xgl         // sub-window ?
 28036        xgl           {
 28036        xgl             Window xw;
 28036        xgl             xw = xEvent.xvisibility.window;
 28036        xgl             while (cWin == 0)
 28036        xgl               {
 28036        xgl                 Window rw, *cw; unsigned int nc;
 28036        xgl                 if ( !XQueryTree(dpy, xw, &rw, &xw, &cw,
&nc) )
 28036        xgl                   continue;
 28036        xgl                 if ( cw != NULL )
 28036        xgl                   XFree(cw);
 28036        xgl                 generic.cachedWindow
 28036        xgl                   = [XGServer _windowForXWindow:xw];
 28036        xgl               }
 28036        xgl           }
 28036        xgl 

Can anyone suggest a fix for this?   The XQueryTree code is what seems to be
causing the issue.
