Summary: Widget not contained in stack error with ENABLE_THREADEDGL
Initial Comment:
Running the avogadro binary freshly compiled from HEAD crashes. Binary compiled and run on Ubuntu 10.04 64-bit with ENABLE_THREADEDGL=ON. Turning this off does not produce this bug.
Here is some gdb output that might be helpful.
