This means that QT-Ruby most likely has a memory problem. libselinux is just freeing memory in its destructor that it allocated when it started. Somehow qt-ruby has overridden this memory. libselinux is used in thousands of applications and this code executes cleanly in all of them. But we have seen several apps with memory problems have problems with libselinux cleaning up after itself in the destrutor.
