TOA freezes and crashes continuously

Hi, i got a problem with Twilight of Arnor v1,91.

When im playing the game in a quite advanced phase, and the other civs have already many ships etc, game freezes and some times even crashes when i:

- hit turn button

- jump to another location with the mini map

- move the cam to an area of the map i havent used much

- build a new starbase

In general i feel it freezes when the game has to generate something new, like new events in the beginning of turn, new objects like ships and starbases or new textures for planets i havent been watching for a while. My computer is a acer aspire laptop, AMD Turion dual core TL-50 cpu clocked at 1,6 Ghz, 2GB DDR RAM, 400MB Nvidia GeForce Go 7300 Turbocache. So basicaly its not a gaming machine but its quite powerful, and it always rauns the game very well, exept the freezes of course. I tried to decrease graphics but even at lowest graphics the problem persists.

Here is the debug.err message:
