If the application itself is missing files it needs (schemas,
ui files, .la files, whatever), then yeah. If it's some plugin
that's busted, this is how I'd write my application code in a
language with real exception handling:

try:
    load_some_extension()
except:
    warn("This extension sucks. I'm disabling it and moving on.")

Of course, GLib is C. We don't have exceptions. We have GError,
which is a decent foundation for exceptions in language bindings.
But if we don't use it, then languages that could otherwise do
the right thing are screwed.
