No, it's not,  I managed to track it down to gistCmodule.c

In the switch to the new version, they forgot to register with gist a 
function that cleans up the high-level list of graphics engines when a 
destroy event occurs.  So, the high-level was eventually trying to 
reference a destroyed window.  The fix was to just register this 
function (which already existed).  

I've checked in the updated version that doesn't segfault for me anymore.
