[Therion] Loch fails on Fedora 30

Hello everyone - I just noticed that Loch no longer works on Fedora 30. I use the version that is packaged by JM Begley. Launching from a KDE menu spins an hourglass for about 2 seconds and then goes away. When launched from a command shell, the only output is "Error: glXCreateContext failed". This happens on both my laptop and desktop, which have two different display drivers. It also happens on a VirtualBox guest. Is there a way to get a more detailed log file? Thanks! -- Bill Gee
