Hangs while setting options, crashes when quitting the game

[Conan-Kudo]

While testing IceBreaker with sdl12-compat on Fedora Linux 34 on KDE Plasma, I noticed that IceBreaker hangs when trying to set options and crashes when I quit the game.

One such backtrace from GDB:

Before I got the backtrace, I thought it might have something to do with swapping SDL implementations, but the backtrace seems to indicate that it's basically IceBreaker code.

Note that IceBreaker does not run on Fedora KDE Wayland unless you swap to sdl12-compat, which you can do with my COPR.

This is happening with icebreaker-2.1.3-1.fc34. I haven't had a chance to test if icebreaker-2.2.0 would fix it.

Hmmm. I am not surprised if the problem is in the icebreaker code. It is old and bad (and not necessarily in that order). 😄

This problem is only with the compat package? I'll try your COPR when I get a chance and see what I can find.

2.2.0 is just changes to MS Windows build options so shouldn't be relevant.

Well, IceBreaker doesn't run at all with SDL on Plasma Wayland. It chokes saying it can't find a display driver to load.
