Description checkx42 2018-02-22 21:30:27 UTC

Application: plasma-discover (5.12.2)

Qt Version: 5.10.1
Frameworks Version: 5.43.0
Operating System: Linux 4.15.3-2-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
Discover crashes whenever I try to upgrade my Archlinux install using the Software Manager. I usually use pacman, so this feature isn't relevant for me, however, it's a hit or miss chance whether Discover works as intended. The problem wasn't present in the previous package plasma-discover (5.12.1)

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

Please provide more information. Debug symbols would be great.

I use it usually on ArchLinux and never saw this crash.
