SUMMARY
Tested on digiKam 9.0.0 and digiKam 9.1.0 (both appimages) on MX Linux 25.1
(Debian 13) and Samsung Galaxy s25 with BubbleUpnp and VLC. BubbleUpnp can list
photos shared by digikam (miniatures are visible), but fails upon opening a
photo with error "Error downloading image from server". VLC can list photos
(can see their names) but upon opening all is seen is a black screen.
STEPS TO REPRODUCE
1. Start digiKam appimage via terminal and observe messages
2. Share an album with DLNA (ie. Tools -> Share with DLNA)
3. Connect to digiKam DLNA server via BubbleUpnp, try listing shared media and
opening a photo
4. Or connect to digiKam DLNA server via VLC, try listing shared media and
opening a photo
OBSERVED RESULT
Let's focus on BubbleUpnp - I tested also via VLC to confirm if other tools
also have the problem.
So, upon opening a photo via BubbleUpnp, there is the error "Error downloading
image from server". At the time, in the console, I have:
# upon starting the DLNA server:
unknown: No event config could be found for event id "mediaserverloadstartup"
under notifyrc file for app "digikam"
# upon opening a photo (ie. 1062.jpg) in BubbleUpnp
Digikam::MetaEngine::Private::printExiv2ExceptionError: Cannot load metadata

Digikam::ExifToolParser::loadChunk: Cannot open source file to process with

Digikam::DMetadata::loadUsingExifTool: Load metadata using ExifTool failed...
The message "Nie można było otworzyć źródła danych: Nie ma takiego pliku ani
katalogu" is in Polish and translates to “Could not open data source: No such
file or directory.”
What strikes here, are the paths, eg.
home/ben/Obrazy/funstuff/manjaro_pics/1062.jpg
Should it not be like this (notice the preceding slash):
/home/ben/Obrazy/funstuff/manjaro_pics/1062.jpg
?
EXPECTED RESULT
BubbleUpnp opens a photo correctly (no errors logged on either side)
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: MX Linux 25.1, xfce
ADDITIONAL INFORMATION
The problem was also in some previous version of digiKam - though not sure
which, maybe 8.6.
