-- Information about the crash:
- What I was doing when the application crashed:
	1) Open my phone folder throught KDEConnect
	2) Start moving files from phone to local folder
	3) Lose connect to phone
		3.1) Dolphin show Dialog window "File not found[retry,cancel ...]
	4) Restore connect to phone
		4.1) I check what connection restored open my phone folder and show image file
	5) Click retry in Dolphin dialog window(stage 3)
	6) Dolphin crash
- Unusual behavior I noticed:
When i continue moving file after lose and restore connection, Dolphin say what file already exist and sizes files equals but in destination folder file is broke. 
Something Dolphin show two dialog`s window.
