Log:

change database usage. The conversion from and to utf-8 is done implicitly

Qt4's QSqlQuery tries to insert NULL for null values. Calling .toUtf8()
on an empty but non null QString will result in a null QByteArray.
Inserting the null ByteArray into a non NULL field will consequently fail.
I reported it to Trolltech but I don't expect them to fix it in a timely
fashion if at all. The behaviour hasn't changed. Upstream ticket number
is 189442. The change is in QSqlQuery.
MSqlQuery::bindValue() and value() will do the conversion implicitly
and handle empty string correctly.
I hope I removed the {from|to}Utf() from all queries.
