When I start Wireshark on Windows 10 (development, Release build), I get an
immediate crash. I switched to Debug build and was able to trace the problem
to the df_combo_box_ member variable being NULL in MainWindow::resizeEvent.
The patch below fixes it, but I'm worried it's masking the symptom of a bigger
problem (otherwise I would just push the patch).
