When opening the preferences while capturing I get two different crashes with
and without "Hide capture info dialog".  This is observed on OSX.



1. Start a capture with "Update list of packets in real time".
2. Open the "preferences"
3. Wait until some packets are captured
4. Press "OK" in preferences
5. Stop the capture
