Hi James -
I have exactly the same version of mesa-libGL as you mention below. Below is what rpm -qi has to say about it.
I see that I have both 32-bit and 64-bit packages installed. Is it possible that Loch is getting confused about which to use? Answering my own question: I tried Loch on a VirtualBox machine that runs 32-bit Fedora 30. Same error.
I rarely use Loch, so figuring out when it stopped working is an exercise in futility. About the best I can say is it was probably working late last year (2018). I know it worked at one time ... Having a working Loch is one of the reasons I switched to using your copr packages instead of compiling from source. In all the years I compiled Therion from source, I always had to turn off the Loch component because it would always fail. I was excited to have it finally work! :-)
Regards - Bill Gee
