Sentry Crash Report:

Description JBlack 2018-05-21 07:38:47 UTC 
Application: dolphin (18.04.1)

Qt Version: 5.10.0
Frameworks Version: 5.46.0
Operating System: Linux 4.13.0-41-generic x86_64
Distribution: KDE neon User Edition 5.12

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

I opened dolphin, then closed it.   A few seconds later a crashed message popped up stating that "dolphin closed unexpectedly"  - This is seems to happen every time I close dolphin.  It doesn't hinder my day to day work but it certainly is annoying.

The crash can be reproduced every time.

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

*** This bug has been marked as a duplicate of bug 393528 ***
Comment 2 Christoph Feck 2018-05-21 21:35:08 UTC 
Elvis, this ticket is from Dolphin 18.04.1. If this is indeed a duplicate, then bug 393528 is not fixed.
Comment 3 Elvis Angelaccio 2018-05-26 13:42:18 UTC 
Hmm, indeed. The stacktrace seems the same though, weird.
Comment 4 Elvis Angelaccio 2018-06-03 10:55:48 UTC 
So, on master we have dolphinmainwindowtest crashing with the very same backtrace, so this indeed is not bug #393528.

The crash is caused by the lambda slot in PlacesItem::setUrl(). I'll push a patch that fixes the dolphinmainwindowtest crash and should hopefully also fix this crash.
Comment 5 Elvis Angelaccio 2018-06-03 11:19:36 UTC 
Git commit 588abbf1b6994245d987c0d07c2b074cb76fc034 by Elvis Angelaccio.
Committed on 03/06/2018 at 11:08.
Pushed by elvisangelaccio into branch 'Applications/18.04'.

Fix crash in PlacesItem::setUrl()

Connections to lambda slots without context/receiver argument can lead
to crashes, because if the receiver is deleted Qt won't delete the connection
as it normally would when the receiver is specified.

This patch moves the slot from the lambda in PlacesItem (which is not a QObject)
to PlacesItemSignalHandler. This fixes the `dolphinmainwindowtest` crash
we currently have on master, and should also fix bug #394507 which has
the very same stacktrace.
FIXED-IN: 18.04.2
