All clustered very close to 7AM UTC, but for a number of different *_text_parsed fields.
But I just realised it is in a customised lang.php, and '*_text_parsed' instead of '*__text_parsed', so it was probably a typo in your override.
In fact, it was probably an attempt to fix what you thought was a typo in the original cause, that you thought caused the original issue here. Sometimes we use '__' instead of '_' just to make a clearer separator from the rest of a name which may itself involve underscores.
I am looking at the JavaScript issue now.
The inline editing issue will be fixed for RC2.
I am also reviewing your error log.
