Comment 1 Janek Bevendorff 2016-05-25 13:41:15 UTC 
I can confirm regular crashes when deleting files (Shift+Del).
Since Arch doesn't provide debug symbols, I can't provide a stack trace right now, but from the description I would guess that this is the same bug.

Here some observations:
- The crash mostly seems to occur when I have multiple tabs open.
- I usually delete multiple files at once
- Dolphin doesn't crash immediately, but freezes for about 2 seconds before actually crashing
- Move-to-trash is really, really slow (and I mean REALLY slow, like 5 seconds or more) while instant delete with Shift+Del is actually instant, but sometimes crashes Dolphin

The first two may be coincidence, the last one may be a different issue, but I maybe that information helps.
Comment 2 Janek Bevendorff 2016-05-25 13:47:24 UTC 
The crash also occurs when renaming files sometimes. I'm in the process of renaming and moving a lot of files manually and I'm having a really hard time because Dolphin crashes every couple of minutes.
Comment 3 nanohard 2016-06-11 21:01:42 UTC 
Same as 356801?
https://bugs.kde.org/show_bug.cgi?id=356801

I commented on that bug. Crashes when deleting a file or trying to empty trash.

Update: I've gotten this working now (Arch OS). I removed all phonon-qt*-vlc packages and installed phonon-qt*-gstreamer. I also installed vlc, which I thought was installed, but wasn't. Now neither dolphin nor systemsettings5 crashes on me.

Phonon uses qt4 instead of qt5, not sure why then that the package phonon-qt5 even exists alongside phonon-qt4. But removing those phonon-qt[4/5]-vlc packages and then installing phonon-qt[4/5]-gstreamer AND installing vlc was the answer for me. I'm not sure if only installing vlc may have solved this, but whatever.

I had the same bug on Arch linux (Plasma 5.6.5, framework 5.23.0, Qt 5.7.0) and I tried to install vlc. As it was already installed, I let pacman reinstall it and the confirmation dialogs for "empty trash" and "delete" don't crash anymore. It seems to be linked only with vlc as I have phonon-qt*-vlc installed. The post-transaction hooks are:
        (1/4) Updating icon theme caches...
        (2/4) Updating manpage index...
        (3/4) Updating the desktop file MIME type cache...
        (4/4) Updating the vlc plugin cache...
so it could be a faulty cache that causes the crash...

Replacing phonon-qt[4/5]-vlc packages with phonon-qt[4/5]-gstreamer worked for me.  Thanks!

For the record, vlc should have been installed, since it's a direct dependency of phonon-qt[4/5]-vlc.  It was for me, but dolphin was still always crashing with any delete attempt (Shift+Del), so that shouldn't be related.

Reinstalling vlc (with only vlc backends and not gstreamer backends installed) also worked for me.  Thanks!

system: Arch 64-bit, up-to-date, KDE Frameworks 5.26.0, Qt 5.7.0, Dolphin 16.08.1
phonon-qt[4/5]-vlc still at version 0.9.0-1 (built April 2016)
