Not currently clear what has caused this - maybe an invalid match expression?

I can't reproduce the error just by copying the bit of pmatch expression from the error message into a new question.

To progress this, we will need more information. Can you find the question that triggered this error? (Try searching in the question_answers table in the database for match_mw (less*| or something.

If you find the question, can you edit and/or preview it? If so, can you reproduce the error?

We're not yet able to reliably reproduce it either; working on it.
