This does not fix the Qt UI issues I have.

I'm getting a crash when updating a protocol preference by second-click the
packet in the tree view and selecting something which triggers a redissect. 
The crash happens in setMenusForSelectedTreeRow() line 1268 where edt->pi is
released memory.

To reproduce:
>From https://wiki.wireshark.org/SampleCaptures download dmp-examples.pcap and
configure DMP to use port 24209.  Select the first packet, second-click on DMP
in the tree view and change "National decoding".  This will trigger a "Use of
deallocated memory detected" if running with AddressSanitizer / ASAN.

I'll investigate some more.
