Application: kdeconnectd (0.1)
KDE Platform Version: 4.14.5
Qt Version: 4.8.6
Operating System: Linux 4.4.11-desktop-1.mga5 x86_64
Distribution: "Mageia 5"

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

I clicked a notification's X to remove/clear the notification. I've done this action many times before without crashing.
The only difference this time I can see is that the phone was turned off but was still showing in kdeconnect.

- Unusual behavior I noticed:

kdeconnect crashed.

-- Backtrace:
Application: kdeconnect (kdeconnectd), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
