Linux: Immediate segfault when starting from a terminal

[Lokasenna]

As the title suggests, starting Reaper from a Linux terminal is immediately crashing with a segfault. After some help from cfillion I was able to come up with:

Reading symbols from reaper...

This happens with or without -cfgfile specified, on both v6 and v5.984.

Running Ubuntu Studio 19.10 + XFCE's terminal.

It's an ASUS ROG laptop, probably five years old.

For completeness I should add that running it from my launcher continues to work just fine.
