Hi,
I think these two assertions, in packet_list_compare_records()
g_assert(a->fdata->col_text[sort_id]);
g_assert(b->fdata->col_text[sort_id]);
are not quite correct.
If you click abort while constructing columns, it'll lead to:
ERROR:packet_list_store.c:955:packet_list_compare_records: assertion failed: (a->fdata->col_text[sort_id])
IMHO it should be possible to abort constructing columns - and it should not abort program.
By the way, it would be nice if columns only for visible_rows will be generated & sorted - not all of them :)
