Translated plugin strings displayed like code after settings saving

[SlavaP]

this seems to happen when there is no language file available at the moment,
but it will go away as soon as a valid language file whith that string is detected

Of course but why?

i think its a bug with the il8b Gallery plugin, I get this all the time.
its only after a save.

As you can see in the bottom of the picture the bug was replicated in another plugin (maintenance)
