[Therion] loch segmentation fault at launch

[Bill Gee]

Testing out Therion 6.2.1+dev, I find that loch does not work.  When 
launched from a command line, it runs for one or two seconds and then gives

bgee at main2:~$ loch
Segmentation fault (core dumped)
bgee at main2:~$

This is on Fedora 41, and it happens on several machines.

If it helps any, I captured the core dump file and put it on a server.
