Description Patrick Silva 2018-12-25 19:38:37 UTC

Application: plasma-discover (5.14.4)

Qt Version: 5.12.0
Frameworks Version: 5.53.0
Operating System: Linux 4.19.12-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I forced Discover to quit after a freezing, now Plasma shows crash notification immediately after I click Discover icon in the apps launcher.

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".

As per https://bugs.archlinux.org/task/61198 this is caused by flatpak 1.1.2. I can't reproduce it myself, though

I confirm, I just tested it on Arch Linux:
Discovery crashes when flatpak is present;
if I remove it, it works again without problems.

Comment 9 Aleix Pol 2019-01-08 16:05:57 UTC

I've been working on it with flatpak devs and it seems like an upstream issue nobody understands. :/

Comment 12 Nate Graham 2019-01-14 17:17:38 UTC

Fixed upstream in Flatpak with https://github.com/flatpak/flatpak/commit/f9c6a769ef30a3a33038ec91f080197a0bf418a5

They've just tagged 1.1.3, so hopefully it should be released and in the wild soon!

flatpak 1.1.3 is already available on Arch Linux, I can confirm that the crash is fixed.

Comment 15 Nate Graham 2019-01-15 21:21:33 UTC

Thank goodness! Thanks Patrick.
