-- Information about the crash:
- Custom settings of the application:
not settings
i'm using "mimeinfo -d ..." and choose dolphin4 (#1), but i see gtk warnings (not seriously) and:

Error: "/var/tmp/kdecache-..." is owned by uid 1000 instead of uid 0". I'm used sudo chown root.root /var/tmp/..., but not results... :(

I just want open folders with dolphin when using chromium "Show in folder", but it's opens strange file manager (i don't know what is it...).

I'm using i3. I purged KDE (i using i3 and not using kde4, because i have i3 (well, just i more like i3, but i used KDE more and i know that i do).

Thanks you more! :)

The crash can be reproduced every time.
