Comment 1 Julian Steinmann 2018-07-24 18:27:34 UTC

Hmm, Dolphin starts just fine for me with KDE Neon User edition. This might be a distro-related issue, but that's hard to tell. Since when does this crash happen?

Comment 2 apolanec 2018-07-25 07:12:27 UTC

I am not exactly sure, i think i notice it about 2 weeks ago, i am not sure which update caused it, but i update my system(tumbleweed suse) almost daily.

Comment 3 Julian Steinmann 2018-07-25 08:11:40 UTC

Okay, according to the OpenSuse Tumbleweed package history two weeks would match up pretty well with the release of Dolphin v18.04.3, so it's likely that a commit between 18.04.2 and 18.04.3 is causing this crash for you. One thing that you could try is to backup all configuration files of Dolphin (~/.config/dolphinrc and the view properties in ~/.local/share/dolphin/) and then delete the originals to check that this is not a configuration related problem.

Comment 4 apolanec 2018-07-26 10:57:30 UTC

I will try it.

Comment 5 apolanec 2018-07-26 14:58:12 UTC

I deleted  ~/.config/dolphinrc and the view properties in ~/.local/share/dolphin/,
and a new window keeps crashing.

Comment 6 Elvis Angelaccio 2018-07-28 15:29:14 UTC

Do you have the global menubar enabled in Plasma?

Comment 7 apolanec 2018-07-30 07:11:16 UTC

yes, i believe i do.

Comment 8 apolanec 2018-07-30 09:22:52 UTC

I removed it and now the problem is gone.

Comment 9 Nate Graham 2018-07-30 23:04:32 UTC

Thanks for the info!
