Qt Wireshark will crash after using the Expert Information fetaure.   The crash
will happen on program exit if the Expert Information window was only opened
one time. Or Wireshark generally will crash when a second attempt is made to
open the Expert Information window.  More rarely Wireshark will crash simply
when closing the first Expert Information window.  Occasionally one can open
the Expert Information window a second time but Wireshark will crash when the
window is closed.  This problem has been replicated on both OS X and Windows. 

Steps to reproduce:

1 - Open Qt Wireshark

2 - Open a tracefile (for example the small example attached to this bug).

3 - Open the Expert Information dialog by either clicking on the small round
widget in the bottom left corner or by selecting the menu item Analyze / Expert
Information.

4 - Close the Expert Information window by clicking on the [Close] button.

5 - Either Exit Wireshark (choose File / Exit) or reopen the Expert Information
dialog a second time.

6 - Wireshark will crash.
