Wireshark-dev: [Wireshark-dev] Crash when opening the preferences while capturing

Hi.

When opening the preferences while capturing I get two different crashes with and without "Hide capture info dialog". This is observed with latest svn (21469) on OSX. Is this known errors?



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
