Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

Thank you, this solves the problem.

Glad to help ! ;)

Developer response:

Delete the bundled libSDL2-2.0.so.0 in the lib64 folder and it'll use your system's version instead. Somewhere down the line there was a DBus change that broke compatibility, so an SDL update is needed to fix this.

Will forward this to the current maintainer so we can get an official fix out, but that's the fast way to work around this for now!

The workaround works on 32-bit too:

cd ~/GOG\ Games/Bastion/game/lib/
mv libSDL2-2.0.so.0 libSDL2-2.0.so.0.bad
sudo apt install libsdl2-dev

Lauching Bastion now works.
Installing libmono-2.0-dev does not seem to be required. What's about fixing the GoG's installer itself, 6 months after the issue was addressed?
