<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Thanks Albert. I just got a chance to look at this this morning. I was going to suggest that r should probably be class static instead of file static, but that's really not such a big deal. I snooze, I loose. Thanks again.</pre>

I managed to reproduce it locally and the backtrace is

The problem is caused because our KGameRenderer is a K_GLOBAL_STATIC that uses a pen that is a Q_GLOBAL_STATIC and depending on the destruction order it may happen that the QPen is destroyed first and then bad stuff happens.
I've workarounded the issue by making the KGameRenderer not be a K_GLOBAL_STATIC anymore and adding a specific cleanup() call</pre>
