Description sloppedmail 2021-07-20 13:06:29 UTC 
If an image is located in a NTFS partition and its file path contains a '#', it cannot be selected in the wallpaper menu.


STEPS TO REPRODUCE
1. Create NTFS-Partition
2. Place image in a folder that contains a '#' (e.g.: .../#images/image.png)
3. Add image as wallpaper (right-click desktop -> configure -> add image)


OBSERVED RESULT
The image thumbnail shows up in the list, but cannot be selected. Clicking on said image automatically selects a different (default) image


EXPECTED RESULT
The image should be selectable and appliable


SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux
KDE Plasma Version: Plasma 5.22.3
KDE Frameworks Version: 5.84.0
Qt Version: 5.12.2


ADDITIONAL INFORMATION
* This only seems to occur on images located in NTFS partitions. Ext4 works fine
* Affected images cannot be removed, even after deleting the file
* You can add the same image multiple times
* Duplicates disappear after restarting the program

Appareantly it's NOT just NTFS, as the same thing happens inside my home-directory on a normal ext4 partition (I messed up while testing earlier)

The same issue is also present on the newest stable KDE Neon (tested in a live environment)

Observations:
If a parent-folder has a '#' in it, the image cannot be selected. If the file-name has a '#', it can be selected, but cannot be applied

Some quick notes:

It goes wrong in the config dialog.

/home/david/#foo.jpg

gets saved as:
usersWallpapers=/home/david/foo.jpg

in plasmarc

It strips the "#" character, it doesn't truncate to that point, so it's not treating it as a URL fragment

int BackgroundListModel::indexOf(const QString &path) const
{
    for (int i = 0; i < m_packages.size(); i++) {
        // packages will end with a '/', but the path passed in may not
        QString package = m_packages[i].path();
        if (package.endsWith(QChar::fromLatin1('/'))) {
            package.chop(1);
        }
        // remove eventual file:///
        const QString filteredPath = QUrl(path).path();

That obviously fails encoding/decoding
