hi étienne, can you change

#. translator : Add you in this field
#: ../src/flegita.c:73
msgid "Not translated"

to the msgid "translator-credits" (it's the most common name for this) and change the comment to something like
  Translators: Add your names here with one name per line, like
  "John Smith <email1@example.com>\n
  Robert Foo <email2@example.com>"
so they understand that they should add their names? this is not clear at all, see bug 519626.


other issues:

#: ../lib/gnome-scan-dialog.c:476
msgid "Scan"
noun or verb? -> translator comment.

#: ../lib/gnome-scan-dialog.c:514
msgid "Unable to detect scanners !"
#: ../lib/gnome-scan-dialog.c:521 ../lib/gnome-scan-dialog.c:890
msgid "No device found !"
please remove any trailing whitespaces from exclamation marks.

#: ../lib/gnome-scan-dialog.c:653
#, c-format
msgid "%s:"
what's that?

#: ../lib/gnome-scan-dialog.c:1392
msgid "Inactive"
like "not busy", or like "you cannot click on it, it is greyed out"? it's a difference in my language.

#: ../lib/gnome-scan-paper-size-widget.c:71
#, c-format
msgid "%.0f x %.0f mm"
how to translate properly? i guess "mm" is "millimeters"? translator comments.

#: ../lib/gnome-scan-param-widget.c:119
msgid "ms"
msgstr "ms"
what's that? milliseconds?

#: ../lib/gnome-scan-preview-plugin-area.c:486
#: ../modules/gsane-meta-param.c:331
msgid "Manual"
the handbook, or non-automatic? -> translator comment.

msgid ""
"Color enhancement produce better photos, but take more time to process and "
"can be useless for text."
either "enhancements" or "produces" and "takes"

#: ../src/flegita-sink.c:106
msgid "Action over the scan output"
what does "over" exactly mean here?

#: ../src/flegita-sink.c:148
msgid "Higher level mean lower file size, but take more time to save"
either "means" and "takes", or "levels"




from /modules/gsfile-scanner.c:
   GObject *object = g_object_new (GSFILE_TYPE_SCANNER,
				"name", (!count ? _("Files") : 
				g_strdup_printf (_("Files (%i)"), count)),
				"blurb", _("Import from files."),
				"icon-name", "gnome-mime-image",
				NULL);
   count++;

this needs proper ngettext support, see http://live.gnome.org/TranslationProject/DevGuidelines/Plurals . current code will never work for a lot of languages. it also leaks memory i think.
