Did you check QSqlDatabase::lastError()? Might give you a clue. I'd
also check any logs generated by the DBMS to see if a table has become
corrupted or some such thing.

It's driver-dependent. You might want to check what
QSqlDatabase::lastError() returns or look at the code of the driver you
use, find the function/query used to begin a transaction and read the

reluctant to add changes to such a central part of Qt. The new templated
connect already has a tendency to produce verbose and noisy error messages
