Short version: after finally updating all my Linux machines to the latest version of Ubuntu/KDE, I can no longer run my Drupal 7 test environments. This means I can no longer test any changes to Eviscerati.org, which makes me uncomfortable.
Drupal 8 runs fine though. Which means... ugh, I don't even want to say it. I may have to migrate the site from D7 to D8.
