Comment 5 for bug 1878336

I do not get this behavior on Debian Bullseye/11

On my debian, after the file is deleted on disk the background goes black on any subsequent change to Wallpaper mode, and `pcmanfm-qt` doesn't appear anywhere near the top of `htop` (ie. no 100% cpu thread)

guiverc@dc780-deb:~/wallpapers$ apt-cache policy pcmanfm-qt
pcmanfm-qt:
  Installed: 0.14.2~166-g74a6f4d-1
  Candidate: 0.14.2~166-g74a6f4d-1
  Version table:
 *** 0.14.2~166-g74a6f4d-1 500
        500 https://lxqt.debian.net/debian experimental-snapshots/main amd64 Packages
        100 /var/lib/dpkg/status
     0.14.1-3+b1 500
        500 http://ftp.iinet.net.au/debian/debian testing/main amd64 Packages

however this maybe a later package than I tested on Lubuntu; the command `pcmanfm-qt --version` both report the same version

guiverc@dc780-deb:~/wallpapers$ pcmanfm-qt --version
pcmanfm-qt 0.14.1
// identical version reported on Lubuntu 20.10
