Application: dolphin (16.04.3)

Qt Version: 5.7.0
Frameworks Version: 5.24.0
Operating System: Linux 4.4.0-31-generic x86_64
Distribution: KDE neon User Edition 5.7

-- Information about the crash:
- What I was doing when the application crashed:
I was opening a pretty big compress file (Bz2) ~1.5 GiB, and got and error stating the reading of the file did not reach the end of it. I noticed the other files on the same directory where missing as well as the disk on the devices list.
Checked the power to the hdd and it was cut due to a loose connector, while fastenig it i got the crashed.

- Unusual behavior I noticed:
First a hang, then kwin sort of crashed as well, since the close/minimize buttons disappeared then the whole desktop crashed as well and restarted a moment later with the crash reporting assitant on the panel.
 
This may related to bug 362841
