Unable to use accounts-qt framework in scratchbox. Accounts DB locked

[scifi.guy]

I am trying to use accounts-qt library to create an account from my application. I don't want to mess up with the accounts.db file on my device, so I am using scratchbox HARMATTAN_X86 target. But this simple code fails to execute in scratchbox.

#include <Accounts/Manager>
#include <QDebug>

using namespace Accounts;

int main(int argc, char *argv[])
{    
     Manager mgr;
}

The error when I execute the binary is

vicar-contacts-plugin[20589]: GLIB WARNING ** default - Error initializing DB: unable to open database file
Manager could not be created. DB is locked 
vicar-contacts-plugin[20589]: GLIB WARNING ** GLib-GObject - invalid (NULL) pointer instance

I have tried deleting accounts.db and accounts.db-wal in /home/user/.account to "unlock" the DB. But it didn't help. I am running the binary as user and user has rw on both files. I am not sure which process is locking the files and how to unlock them. Any suggestions?

You can run your code in your device as "developer".
It should not mess up anything.

Thanks gnuton. I was hoping to use scratchbox with Xephyr for initial testing and then deploy to device. But it seems I don't have that choice because of this error.
