--
With 64-bit wireshark-gtk.exe the Statistics->Endpoints window column auto-size
goes bonkers and sets wildly incorrect column widths once the number of
displayed rows exceeds, precisely, 999 entries.

This applies to all the tabs, especially Ethernet, IPv4 and TCP.

Is true with Maxmind GeoIP active and inactive.

-----

A guess is that an array related to column autosizing somewhere was set to 1000
lines long ago when that seemed a ridiculously large number of endpoints. 
Possibly this could pose a security vulnerability due to a table overflow.
