[Arch] Knossos crashes at start up; never actually starts.

So I had no errors with installation, everything installed fine from the AUR package. However, like the title says, Knossos will not start up.

When I try to run it from the command line, this is the output:

INFO:MainThread:launcher.main: Running Knossos 0.13.3 on PyQt5 and Python 3.7.1 (default, Oct 22 2018, 10:41:28)

No window or anything pops up.

Hm... that doesn't seem to be a crash in Knossos itself since it doesn't use malloc_consolidate. I'm guessing one of the libraries is crashing... can you launch Knossos in gdb and get a backtrace for the crash?

Can confirm on Arch Linux with latest git (Python 3.7/ OpenSSL 1.1.1a). gdb --args python /home/cmcging/FreeSpace2/knossos/knossos/__main__.py produces no extra useful output except: malloc_consolidate(): invalid chunk size

Update: This seems to work when building Python 3.6 from source with prefix /opt/FS2 and using PATH=/opt/FS2/bin:$PATH for all the commands in the git readme.

Sounds like it's a bug in Arch's Python packages. Will have to investigate that. Thanks!
