Hi, I'm getting a very strange error on every magit operation I do, making it quite annoying. *messages* shows the following:

error in process sentinel: magit-todos--async-when-done: Process "magit-todos--scan-with-git-diff" failed with exit code 125. Output:"/usr/bin/nice: a command must be given with an adjustment
Try '/usr/bin/nice --help' for more information.
"

I have no idea what that relates to or where I should look in my environment to figure out what's going on. Any pointers?
