Bug 405433

Application: apper (1.0.0)

Qt Version: 5.12.1
Frameworks Version: 5.56.0
Operating System: Linux 5.0.0-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I tried to update my Arch Linux system and Apper crashed. However, it seems like the update has finished since the CLI tool (pacman) reported that there aren't any updates.

-- Backtrace:
Application: Apper (apper), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
