Seeings as you're on Mythdora and I've not used it I was trying to
stay out of this thread.

However I am curious if you run the backend with '-v most' and
pastebin the logs and post the link back here if we'd see something
more meaningful.

Also is .23-release in your version number indicative that you're NOT
following the fixes branch? Someone with more experience with a fedora
based OS might want to suggest how to get the fixes branch on your
box.
