I have an idea, theoretical scenario: isn't it somehow similar problem as with the volatile and synchronization in Java?
GTK makes many updates and redrawing at the same time.
Even Eclipse have parallel threads for redrawing.
I got 2core/4thread CPU Intel i5.

What if the GTK tries to redraw something, but the CPU context switching occurs and then it has invalid references?
All code then seems correct, but it is not.

I see these crashes for maybe two years (perhaps since Kubuntu 12.10),
some were closed as incomplete, one even as fixed (bug in intel driver),
but this problem is still the same.

Maybe I will try some experiments with the affinity and I will see if it will make some difference:

  I tried different version of Java (Oracle v7 and v6 jre) with same
  result. Also, Eclipse display blank menus so there's a general java
  problem with displays.
