[Emmanuele Bassi <ebassi src gnome org>]

commit cd2a1cf4803df61b2621394bc8a1ac6105f063c8
Author: Emmanuele Bassi <ebassi gnome org>

    Fix compiler warnings in the release build
    
    We have a bunch of debug-only variables that get set and never used
    outside of debug code paths, and the compiler is not happy about it.
