I do not see obvious mistakes.

On what line it crashes?
What do NewDB.init() ?


Have you made steps in debugger to see if Db object is not nill ?

Have you try set debugLevel = 2 for Valentina and watch console output ?
Try this, may be you will see some error code from Valentina.

It seems Erne, have utility that do XML dump/load.
Look into archive of V4RB/ThirdParty, it seems vExport project,

Also project _TEST have it in one of tests.
