The executables cannot be wrapped
On NixOS we are wrapping GTK applications using shell scripts. Unfortunately, one of the side effects is that the resources file cannot be found, since scripts ignore argv[0]
on Linux. One of the possible fixes is using a light binary launcher as Polari does: polari@f5dce05b
