Strings.txt list follow tags with qualifiers that will not be received from metaserver
translations/Strings.txt list follow tags to be collected for translation. It includes qualifier to them. As metaserver will not sent them with such a qualifiers, the strings will not match and translation will not be used. I think the only thing we can do is to remove qualifiers, and hope the strings to be unique (or to add qualifiers to other instances).
False alarm. We add the qualifier programmatically when after we receive the tag from the metaserver and before we call gettext to translate it.
Turning this to a documentation ticket to make sure we don't make the same erroneous assumption about the situation again.
New patch version with factual corrections to the comment.
