Description caulier.gilles 2026-01-05 12:10:59 UTC

Context : digiKam Windows bundle
OS : Windows 10 or 11
Qt 6.9.1
KDE framework 6.17

At startup digiKam use Solid API to identify disk UUID. Nothing special here in digiKam code. If you are interrested all code relevant of Solid are located in this source code:

https://invent.kde.org/graphics/digikam/-/blob/master/core/app/main/digikamapp_solid.cpp?ref_type=heads

https://invent.kde.org/graphics/digikam/-/blob/master/core/libs/dialogs/solidhardwaredlg.cpp?ref_type=heads

With DebugView, Solid API report broken signals and slots as these one:
...

Please fix these broken signal and slots connections.

Cheers.

Comment 1 Maik Qualmann 2026-01-05 19:44:59 UTC

That was the solution for Linux (fstab), since the messages were also present there at one point.

@Gilles, I think I saw them on macOS too; can you confirm that?
