New version of Patch

Hi Gilles,
see attached the patch. To update the paramters in CoreDbAccess according to
the dbEngineParameters, I call setupdatebase.cpp:
CoreDbAccess::setParameters(params);

See the complete snippet here:
if (d->databaseWidget->getDbEngineParameters().ignoredDirectories !=
d->databaseWidget->orgDatabasePrm().ignoredDirectories)
    {
        qCDebug(DIGIKAM_GENERAL_LOG) << "Ignored directories settings changes.
Update...";
        DbEngineParameters params = d->databaseWidget->getDbEngineParameters();
        settings->setDbEngineParameters(params);
        settings->saveSettings();
        CoreDbAccess::setParameters(params);
        ScanController::instance()->completeCollectionScanInBackground(false);
    }

But unfortunately, this crashed the hole application:
*** Error in `/opt/kf5/bin/digikam': double free or corruption (fasttop):
0x00007fffc00dcbe0 ***
Program received signal SIGABRT, Aborted.

Do you know a way to update the parameters in CoreDbAccess correctly?
