Wolfgang, thanks a lot for explanations.
Sounds like Qt5 is using its own file dialog, instead of KDE's.
As I do have KDE3 installed here too (though I haven't used it since 8 years or so) I just gave it a try, and the latest okular did use the KDE file dialog here. So it definitely is "compatible with KDE3". i.e. KDE3 is detected as KDE session by Qt5.
Qt5 tries to adapt itself to the desktop in use even more so than Qt4 did. It does so by detecting the desktop in use and then loading an appropriate plugin. KDE's plugin "tells" Qt5 to use KDE's file dialog instead of its own (amongst other things).
Apparently you don't have that plugin. Try to install the package "plasma5-integration-plugin".
You are absolutely right, installing plasma5-integration-plugin resolved the issue.
From the other side I have other KDE5 applications (e.g. digikam) that work correctly.
That's strange though, I would expect digikam to use Qt's file dialog as well then (instead of KDE's). And that's what it does here if I uninstall plasma5- integration-plugin according to what I tried just now.
OTOH, there is not much use of file dialogs in digikam normally, is there? (I'm not really using it myself)
You are probably right here again, I've just briefly tried digicam and probably have not used save/save as yet.
Thanks again & regards.
