QUrl has static functions to convert a qstringlist and vice versa, makes for less code.

Two thoughts on this though:

1. The PathEntry functions make little sense here. All they do is inject $HOME which makes no difference here unless we assume users tend to rename their home a lot. It might well be wise to change to the regular read/write functions. We'd then have a template reader [1] so we can read into a `QList<QUrl>` directly and write from one as well. We lose nothing but get smoother code and it would be faster as it doesn't have to substitute $HOME all the time. So if you are interested migrating away from the Path entries would be a good project.
2. Additionally if you fancy some work on framworks, I think KConfigGroup would benefit from having `readPathEntry(char*, QList<T> &aDefault)` as a template function like the one at [1]. It would behave like the QStringList function but then use a default constructor `T(string);` to put the expanded string into a template object. In terms of QUrl that would allow us to get rid of excess list conversion by simply using a `QList<QUrl>` template default and having KConfigGroup feed `QUrl(string)` objects into that.

Eitherway, if you change to the QUrl helpers for list conversion this should be good to ship.

    Why is this change needed?
    
    Also, for future reference. Please init one object at a time
    
    ```
    clear = new
    clear.setText
    ...
    connect(clear, ...)
    
    remove = new
    remove.setText
    ...
    connect(clear, ...)
    ```
    
    It's easier to read that way.

    I do not think this can happen, can it?

    We can do this way simpler
    
    ```
    auto list = QUrl::fromStringList(configGroup->readPathEntry("Recent Urls", QStringList()));
    ```
    
    to convert the `qstringlist` to a `qlist<qurl>` and 
    
    ```
    configGroup->writePathEntry("Recent Urls", QUrl::toStringList(list));
    ```
    
    to convert it back.

    Same as with the other code, convert->remove->write
