As for the output of ldd:

libm17n-core.so.0 => /gnu/store/pdwv15zmghndkqy5473v1hxgibmvzvlz-m17n-
lib-1.8.0/lib/libm17n-core.so.0

That'd be big if true, we've had the wip-emacs merge between then and
now and while that caused a lot of problems to many, it should still
open up.

Now, perhaps there's a case to be made, that it's in fact broken on
another architecture or when not using substitutes (it is not
reproducible after all), but atm we're lacking a bit of necessary info
here.
