    I can't to reproduce it.

  8. furszy commented at 2:09 PM on February 19, 2024: member

    It is because the test is trying to access the QMessageBox::Discard button on a dialog that does not have a discard button. It does not happen regularly because SendCoins() usually confirms the SendConfirmationDialog dialog in less than 500ms, which destructs the dialog, only leaving the psbt dialog active by the time the timer is triggered.
