Should this be a following code?
if (resultCode != SQLITE_OK)
    return false;

Why do you need to do 'deleteFile(m_databasePath + "-shm")' twice?

You use checkSQLiteReturnCode in ASSERT macro even though it has a side effect.
The side effect is effective only in Debug build.
Is this intentional?

checkSQLiteReturnCode should be defined as:

void CookieJarDB::checkSQLiteReturnCode(int actual)
{
    if (!m_detectedDatabaseCorruption) {
        switch (actual) {
        case SQLITE_CORRUPT:
        case SQLITE_SCHEMA:
        case SQLITE_FORMAT:
        case SQLITE_NOTADB:
            flagDatabaseCorruption();
            m_detectedDatabaseCorruption = true;
        }
    }
}

This code should be replaced with:

checkSQLiteReturnCode(ret);
if (ret != SQLITE_OK && ret != SQLITE_DONE && ret != SQLITE_ROW && !ignoreError)
    LOG_ERROR("Failed to execute %s error: %s", sql, m_database.lastErrorMsg());

Other ASSERT(checkSQLiteReturnCode(ret, SQLITE_DONE)) should be replaced with a following code:

checkSQLiteReturnCode(ret);
ASSERT(ret == SQLITE_DONE);

Inverse the condition for the consistency.

if (resultText != "ok") {
    LOG_ERROR("Cookie database integrity check failed - %s", resultText.ascii().data());
    return false;
}

return true;

Yeah, step also shouldn't even be returning SQLITE_OK.

Right, that shouldn't have been added.

That looks much better.
