The build has been failing because sourceforge-served release include -Werror=format=2 flag, which enabled -Werror=format-y2k, which in turn stopped the build because of a debug log message formatting. Building release from GitHub works fine.
There were a couple of issue before the application run normally. The first one is GConf error: https://nixos.org/wiki/Solve_GConf_errors_when_running_GNOME_applications The second one is absence of gst plugins: https://github.com/NixOS/nixpkgs/issues/10559
