I had the exact same crash, and persistent on every run and compile 
session. This 1 line fix solves the problem for me, so I like it. I even 
tried to valgrind the issue, as it seemed to me a double free, or some 
other kind of alloc/destruct issue, but as Dirk pointed out some days 
ago, valgrind is basically useless due the excessive noise  from Qt and 
other libs

best,
