If I choose following answers in conversation after completing a quest:
> NPC: Find any antibiotics yet? You: Yup! Here it is! NPC: Oh thank god! I'll be right as rain in no time. You: Maybe you can teach me something as payment. NPC: Here's what I can teach you... You: Eh, never mind. Segmentation fault (core dumped)
it always crashes (100% cases). I dont' know how to check which version I play, but I downloaded it today from github and compiled on Ubuntu 12.04.

Here is the backtrace for that error
Program received signal SIGSEGV, Segmentation fault.
