Bug 356155

Application: dolphin (15.08.3)

Qt Version: 5.5.1
Operating System: Linux 4.0.5-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- What I was doing when the application crashed:

Right mouse click on empty space in dolphin, select "Create new.. -> Folder..." in popup menu, then crash, always reproducible

Extra information:
I see some duplicate entries in dolphin context menu, selecting second option ("Папку..." = "Folder..." in english) does not crash dolphin. I have several DEs installed (LXQt, xfce), so maybe those duplicate entries are from other DEs? And that one that causes crash does not belong to KDE and dolphin sees what he doesn't expect?

Screenshot will be below

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
