The game segfaults when I run it. Here's what I got from gdb:

Starting program: /usr/bin/python3 ./unknown-horizons
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

OK, since I didn't get a reply on this issue yet, I decided to dig into the code myself.

I ran the project through my vscodium setup with the python fault finder enabled. The crash happens on line 109 of run_uh.py import horizons.main

Here's the output from the fault finder:

Fatal Python error: Segmentation fault

So I figured out how to do a backtrace in gdb. Here's the interesting part of the output:

Any ideas on what I should be looking for?

How did you install unknown horizons? And how did you install fife and fifechan?

I built fife and fifechan from the source according to the instructions in the uh wiki. I installed uh by running setup.py

I get the same problem

Guys what distro are you using? And fife/fifechan and uh lastest git version? Or last release version?

@kyrios123

I use Solus it's a x86_64 distro with kernel 5.1.14
Python 3.6.9
fifengine 0.4.2 / fifechan 0.1.5, both built from the latest tarball.

I have the same problem on OSX. Python 3.7.4. unknown-horizons on tag 2019.1 using SWIG 4.0.
After a lot of pain building fifechan and fifengine from master.
I had to remove some build options in fifengine/CMakeLists.txt for it to build. That might influence this?

-  set(CMAKE_SWIG_FLAGS -fastdispatch -dirvtable -noproxydel -fastproxy -fastinit -fastunpack -fastquery -modernargs -nobuildnone -keyword -w511 -w473 -w404 -w314)
+  set(CMAKE_SWIG_FLAGS -fastdispatch -dirvtable -fastproxy -keyword -w511 -w473 -w404 -w314)

python -vvv ./run_uh.py's output ends with

Is FIFE::RenderBackendOpenGL::prepareForOverlays() + 28 the culprit?

I built fife and fifechan from the source according to the instructions in the uh wiki. I installed uh by running setup.py

I did the same and also get a Segmentation fault.

Edit: Using explicitly the versions fifechan 0.1.5 and fifengine 0.4.2 solved the problem.
