Description Tim Steinberger 2018-07-02 00:28:25 UTC

Application: plasma-discover (5.13.2)

Qt Version: 5.11.1
Frameworks Version: 5.47.0
Operating System: Linux 4.17.3-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I just installed packagekit-qt5 and flatpak, and now whenever I start discover it crashes. Discover launches fine without either package (but is obviously useless since no packages are found), and works fine with just flatpak. If just package-qt5 is installed it crashes (though there is already a bug report filed for this). As a side note, I am running Obarun which is based on Arch, and build flatpak from source.

The crash can be reproduced every time.

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

Comment 1 Tim Steinberger 2018-07-03 01:47:27 UTC

This issue is on the package maintainer's end. The crash is occurring because packagekit did not find a file it was expecting. My apologies for not looking closely enough.

Comment 2 Christoph Feck 2018-07-03 02:28:16 UTC

Thanks for the update; closing.
