"No value set in /apps/metacity/general/theme" when using gnome-flashback
Always getting this error when running screenfetch while in gnome-flashback DE. Arch Linux, all packages are up to date. Here's verbose output:

Here's how it looks like:

Sorry for occasional Russian. "Значение не установлено ... " part is "No value set ... ". Also, this message does not disappear with screenfetch -E. Can you please make screenfetch pretty again?

Interesting, will have to spin up Mint Cinnamon and try this out.
Same issue for a while now even on Arch. Same as original poster, I use gnome-flashback:
