The result of LENGTH(<a varchar utf8 field>) varies when ORDER BY is used.

How to repeat:
Load the attached dump file into mysql command line client in latest 4.1 code.

Then run these three queries:

select length(subject) from incidents2;
select length(subject) from incidents2 order by 1;
select length(subject) from incidents2 where ref_no='040312-000057' order by 1;

The first and third return 432; the second returns 176.

Suggested fix:
