[TYPO3-translators] error in LL-XML page and disappearing trasnaltions?

[Stefano Cecere]

it happens only when i try translating sr_feuser_register (in italian)

i get these piece of text in the top html source of the editing frame:


D $labelKey=evalErrors_uniqueLocal_username_informal, $editLang=it,  
$relFileRef=typo3conf/ext/sr_feuser_register/pi1/locallang.xml


don't know if related: but is it possibile that trasnlation disappears, or  
get overwritten when updating extensions?
i am sure i did trasnlate most of sr_feuser_register and  
sr_email_subscribe in the past, and now they are mostly unstranslated!

could it happen in anyway?

thanks
