Most probably the cause of the problem is similar. I hope the following script will fix it:
Culture = 127
Culture = 1033
and not exists(select ID from sf_CmsTextContent t2 where t2.ID = sf_CmsTextContent.ID and t2.Culture = 127)
Please run it into your database and let us know how it goes.
Sorry for the inconvenience.
