Hello ;=)

I have Dolphin that is not working anymore, as soon as i open it it is closed.
If i try to open it in console i have a 'segmentation fault (core dumped)' result.

I'm using Dolphin 19.12.1, Kde plasma 5.17.90, Frameworks 5.66.0, Qt 5.14.0

How can i improve this ?

Thanks

you should file a bug in https://bugs.kde.org, the forum is definitely not a place to file bugs.

But for your backtrace to be useful, you should install debugging symbols first, see also https://community.kde.org/Guidelines_an ... sh_reports

Hello,
I doubt it's a real bug. I saw afterwards i had some debuginfo packages missing, i need maybe 90 of them but then other packages were missing too and i 'm not sure where to find them at all. I guess as i updated plasma after some time some files are not in the right version or going wrong, i'm wondering if i can remove plasma without losing my personal data, and then reinstall to have something clean.

You should not remove Plasma, just make sure all your sources are the same versions. I must admit I haven't used Opensuse in quite some time and I never liked Yast (far too many tweaks needed, too many options and quite confusing), so maybe asking in the Opensuse forums about this might be an idea?

Thank you. I've got an idea that maybe can solve all this. I'll try to go back to the distro provided plasma, but i guess I'll wait for Leap 16 to try it and see if it helps.
