[translations] check_translation crashes

[Jean-Charles Malahieude <lilyfan@xxxxxxxxx>]

Hi all,

As I'm done with the French translations for 2.20, I'd like to now take 
care of 2.21 but… my workflow is now broken and I'm not able to diagnose 
what's wrong. The only change in the body of check_translation.py since 
2009 has been introduced with issue 5646. A "python --version" gives 3.7.6.

Here is the output on the transalation-staging branch (reflecting 
stable/2.20):

-*- mode: compilation; default-directory: 
"~/GIT/Doc-Stable/Documentation/" -*-
Compilation started at Sat Mar  7 10:48:28

make ISOLANG=fr NO_COLOR=1 check-translation > ../../chktrans
langdefs.py: warning: lilypond-doc gettext domain not found.

Compilation finished at Sat Mar  7 10:48:30


And on translation (reflecting master):

-*- mode: compilation; default-directory: "~/GIT/Traduc/Documentation" -*-
Compilation started at Sat Mar  7 10:14:19

make ISOLANG=fr NO_COLOR=1 check-translation > ../../chktrans

Any help in resolving this will be really mostly appreciated.

Cheers,
