For the record:

In this case (when a dialog window appears during the sort) the crash was
caused by a "race" problem. The following pseudo-code reflects the actual
Wireshark code and demonstrates the problem.
sort:
max_row = list_nrows;
for row = 1 to max_row {
columnize_list_row(row); // fill in fields req'd by sort
update_dialog_window(); // processes waiting events (like:
>> // "interrupt" event processed which does the following
>> append_new_row_to_list();
>> list_nrows += 1;
}
sort_list(list_nrows); // fails since appended row(s) not columnized

In these cases (no dialog window ?) I imagine there is a similar "race
condition" as above (altho I don't immediately see the exact mechanism).
============
In any case: SVN #34126 was committed (9/23/10) to disable sorting while a
capture is in progress thus preventing the above scenarios.
It might be nice to find a better solution so that sorts could be allowed while
capturing. See Bug #4273.
