Malformed Headers for Gettext upload
Fragment of a discussion from User talk:Nike
Try replacing the header with one from a fresh download, and check if the msgctxt tags were retained by your gettext editor.
Thanks Siebrand,
I did just that and just manually pasted a header from a fresh download and that fixed the problem.

Our header (using "X" tags) is compliant to the gettext standards. If you see your editor damage the header, please report that as a bug to the supplier of your editor.
