Battlescape logs me out

[excelsior_3000]

Hi Guys,
I'm running ubuntu Lucid Lynx, and UFOAI 2.3. I got it from the PlayDeb mirror on this blog post:
http://www.webupd8.org/2010/05/getdeb-playdeb-repositories-down-what.html

I initially had a similar problem to the dude on this thread:
http://ufoai.ninex.info/forum/index.php?topic=5454.0

that is, the game would just ignore my attempts to get into battlescape

And so I moved the game.so file to /home/USER/.ufoai/2.3/base, and it "solved" it. But this time, instead of ignoring my attempts to get into battlescape, I get a loading screen, and when the tactical battle is supposed to start ufoai logs me out of my OS.

Something similar happens when I'm trying skirmish mode.

Hi. Then we need some logs of a backtrace of the crash (if it is a crash).

Oops sorry.

Here is my ufoconsole.log, trying to get a game on skirmish mode

At this point the game logs me out.
