Love KDE, but it's just too bloated. So I decided to give KDE on OpenBox a shot. Really impressed with the speed, it has all the trimmings I use/need, and it actually looks pretty good.

Problem: the initial file associations set up in KDE proper are not remembered. Everytime I try to open a file in KDE/OB it prompts me for the application to use.

Solution attempt: tried specifying the application and checking the "remember application" box, but the setting is never saved. You have to do this everytime, for every file type.

Anybody seen that, hopefully fixed it?

Using Debian Jessie 8.5, system fully updated at time of posting.

What version of KDE is Debian Jessie currently using? I use several KDE apps with Fluxbox. Unlike previous versions of KDE, KDE 5 apps don't like to be run outside of the KDE environment. I had to add this to my Fluxbox startup file to get everything to behave.

I'm running KDE 4.14.2. Will try your fix anyway.

The plot thickens. I found out how this problems actually happens.

Working in KDE/Plasm, everything runs fine. Then if I logout and load KDE/OB, everything still runs fine. But if I try to change a file association with Right-click>Open With, and check the "Remember application association for this file type" box, then all associations are forgotten and cannot be reset anymore in KDE/OB. I have to logout, load KDE/Plasma and repeat the pattern.

So in essence, everything works fine as long as I don't try to change file associations in KDE/OB. What's really interesting is that the list of system applications that are usually available under the Applications tab at the Kickoff Application Launcher (small K with gear icon on the panel) also disappear.

Tried this with "export XDG_CURRENT_DESKTOP=KDE" in .config/openbox/autostart. I don't think this would be a fix since my KDE apps always loaded fine in fluxbox (using KDE 4.14.2).

I think in Debian Sid, KDE/QT5 apps are still in transition. So without the variable, some apps would load fine, some load without the KDE theme, some would crash and some would appear to work until you tried to apply a setting, then complain it couldn't find something it needed to apply the change.

I'm using Jessie. No but really, never had a problem loading KDE apps in fluxbox. At least the ones I tried.

My problem is with openbox WM on KDE. Original file associations are lost as soon as I try to set one in in KDE/OB, and I have to log back into KDE/Plasma and re-establish the file association concerned.
