It usually indicates a bug in some plugin, which is trying to log some
debug messages to a debug category that hasn't been initialized yet.

You can run your app/code with

 G_DEBUG=fatal_warnings gdb --args ./yourapp

to see where the warning comes from (it will then abort instead of
printing the warning, and you can get a stack trace).
