-clipboard crash with large amount of text

[Harold L Hunt II]

The crash is in xc/programs/Xserver/hw/xwin/winclipboardxevents.c at 
line 565.  The offending code is after a call to:

 /* Convert the text property to a text list */
              Xutf8TextPropertyToTextList (pDisplay,
                                           &xtpText,
                                           &ppszTextList,
                                           &iCount);
ppszTextList is being returned as NULL, yet iCount is > 0.  I have to go 
now, but maybe someone can look up reasons for why 
Xutf8TextPropertyToTextList would return a NULL pointer.
