I have a savegame which crashes every single time for me; i.e. if I just click 'End turn', then it turns on the Alien turn splash screen, some sort of sound effect is played, and then it sits there doing nothing for a long time. If this works for you, then you'll have some fun detective work of hunt-the-hardware-configuration ahead of you.
I'm running the Steam version (if there's any other one) on Debian Sid on a Lenovo Y580 Laptop (Nvidia GTX 660M and some Intel card - the bug happens whether using the Nvidia card via primusrun, or the default Intel card).
If it helps, the OutputLog.txt does spam a big bunch of messages of the form:
[20:00:16]TTextureData::Lock - Locking texture[uitextures/humancitybuttonmask?slow] prior to it being loaded.
