ToME: the Tales of Maj'Eyal

The game freezes the entire system, when chronomancy-related content is used, forcing a manual system restart.
This happens, for instance, when trying to select the paradox mage class in character creation. The game simply freezes my entire system when doing this. I start the game from a terminal emulator, and during the issue the last terminal output for the game is:

[BIRTHER] set descriptor class Chronomancer
Missing race
[BIRTHER] set descriptor subclass Paradox Mage

Also, this first happened when encountering a "weaver young" in game. The last terminal output is now:

Loading tile from tileset /data/gfx/talents/ashes_to_ashes.png

This also resulted in a complete system freeze.

The issue is replicable -at least for myself-, and still occurs in the character creation menu after a fresh download and reinstall of 1.7.4 Linux64 full. The issue occurs after removing all extensions.
extra info: I am using Nouveau as my gpu driver. The game has been running well otherwise.

I don't have the Paradox Mage unlocked yet, but at least with Temporal Warden game starts fine for me.

That probably has something to do with the volumetric shaders the chronomancy talents use and are displayed on the character creation screen. Maybe try to disable them and see what happens?

All of the Chono classes? Temporal Warden works fine for me.

@kurkoasd: What video card do you use? I'm on an ATI and I use the free Mesa driver. Maybe Nvidia has an issue?

Just checked the Character creation screen and the wardens do have a volumetric shader gfx displayed occasionally, so I really don't know.

A fix found.

Thanks for all the replies. @liondriel I have gtx760. The problem indeed was with my graphics card/drivers. I installed the proprietary Nvidia drivers, and the issue now is gone.
Unfortunately, my day was pretty hectic, and I did not manage to test the volumetric shader disabling solution while still running the old Nouveau drivers.
