Bug 398167

Application: kgpg (17.12.3)

Qt Version: 5.9.4
Frameworks Version: 5.45.0
Operating System: Linux 4.18.5-1.g9e91e29-default x86_64
Distribution: "openSUSE Leap 15.0"

-- Information about the crash:
- What I was doing when the application crashed:
I tried to import a gpg signature (.asc file) from dolphin. The file was previously downloaded from the site. It serves to controll for integrity of an app. 

- Unusual behavior I noticed:
While clicking on the asc file you can select kgpg to handel and open the file. This should normally trigger the import of the signature. Instead the application instantly crashed, opening konqi for reporting. 
This is Opensuse Leap 15 with standard KDE and a modified kernel from kernel stable repo (due to incompatibility of the regular distribution kernel with wlan).

-- Backtrace:
Application: KGpg (kgpg), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
