Split strings can’t be translated properly
These constructions in gnome-flashback/libdesktop/gf-icon-view.c
are not translatable:
*message = g_strdup_printf (_("%s names cannot contain “/”."),
is_dir ? "Folder" : "File");
And I don’t just mean that Folder/File are not marked for translation, but also that even then it would be untranslatable in many languages. It’s safer to just have two strings: https://wiki.gnome.org/TranslationProject/DevGuidelines/Never%20split%20sentences
