Version:
Code:
Dolphin 15.12
  KDE Frameworks 5.17.0

  • Qt 5.5.0 (built against 5.5.0)
  • The xcb windowing system
Moving or copying operations in split mode - drag item to other window and drop - results in Dolphin closing down and the "We are sorry, Dolphin closed unexpectedly..." message makes its unwelcome appearance.

I tried two of the workarounds mentioned on these forums:
deleting ~/.local/share/kactivitymanagerd/ - from a remote location while neither KDE or Dolphin were active
switching Appearance>Application Style>Widget Style from breeze to oxygen


Here are my current repos:
Code:
zypper lr -d

Over the last three hours I have logged out, restarted, searched bug reports. I can't see any other solutions.

Are there any other solutions apart from the obvious - don't use Dolphin for moving files.
I mean I can use rsync at the command line but that's for BIG files - two pane drag and dropping gets my vote most times.
I use Konqueror as a file manager too. Dolphin has grown on me over the years

best wishes
