Localization "Password:" string

[Survolog]

Hello!
When I use tools like partition manager I see lost localization for "Password:"
src/policykit agent gui.ui

    <<widget class="QLabel" name="prompt Label">
     <property name="text">
      <string>Password:</string>

In src/policykitagentgui.cpp I found
promptLabel->setText(text);
and

    if (text != QVariant{})
        prompt Label->setText(text.toString());

I dropped that lines and it helps me with localization. But I don't know what I done.
Maybe it will be useful to someone else.

When I use tools like partition manager I see lost localization for "Password:"

Then, the request is non-localized.

I dropped that lines...

Those lines say: "Use our (localized) string if no string is given."
