By the way, I managed to get the backtrace:

which confirm the issue is with setlocale.

About gettext. Indeed gettext-runtime is not called , only glibc gettext
implementation. I shinted to much.

About other gstreamer tools: only the arguments parsed via
g_option_context_parse are breaking (the pipeline parser does not). Thus
stressing gst-launch-1.0 via the only paramaters I found where oe could have
accentuated characters (say a local plugin directory in a home subdirectory
with a non ascii character in its name) i can reproduce:
