Trying to sort on columns other than frame number and time seems to have an odd
issue in the Qt UI.

Specifically if I click on, say, the Destination or Destination Port (added to
check the Qt UI's behavior for bug 11460) then it takes close to 60 seconds to
re-sort my 60k frame capture file (the load time of this file was, according to
the lower-right-hand-corner, 0.5 secs; adding a display filter of, say, "frame"
takes a similarly negligible amount of time).

Where it gets weird is if I then re-sort based on the same or different column
then the sort is very fast.

The Gtk UI does not have this problem.


BTW while looking at the Qt UI's "I'm busy working" interface I do find I
really miss the Gtk UI's "this is how much time I think is left" display.  It
gives me an idea of how long I can go check my email before coming back to find
my results...
