[bug-gv] segmentation fault in gv-3.6.2 + patch

[Jose E. Marchesi]

Hello.
    
    I just built and installed gv-3.6.2 and noticed that some users got a
    segmentation fault when loading their ~/.gv file (as produced by
        State -> Setup Options -> Save
    )
    
    Attached is a small patch correcting the buffer overflow that caused the
    segfault.


Many thanks for your contribution. I will install this patch in the
CVS.
