Hi,
I suspect a problem with update-po, for the new message introduced in
js/messages.php by commit e53fa429808bca3ac3631519a18b7c26761194a5.
Here is what was generated in po/fr.po:
#: js/messages.php:90
msgid ""
"Note: If the file contains multiple tables, they will be combined into one"
msgstr ""
