I just followed the directions to upgrade MythDora 10.21 to MythTV 0.22 and now I can't get frontend to start. On my FE/BE, when I go to run mythfrontend I temporarily get a black screen, and then it just dies. Based on the output when running mythfrontend verbose at a terminal, it looks like the problem might be upgrading the database. Here's the last few lines of output
