Not enough info, I'm afraid; at least two things can modify $text in the writeCompletePage method (where the problem is arising). How do you reproduce this problem? Is the page cache enabled? I don't see this error anywhere in the logs. It can't be confirmed until we can reproduce it.

This was showing up on trunk.foswiki.org, The last time it occurred was back on Jan. 29, 2013. Nothing since. I think we can close this and re-open if it recurs.
