Description Maik 2016-11-05 12:22:17 UTC

Application: plasma-discover (5.8.3)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.4.0-45-generic x86_64
Distribution: KDE neon User Edition 5.8

-- Information about the crash:
- What I was doing when the application crashed:
Apply system updates from tray, Loding..., click around in plasma-discover until you see the list of updates available, click update all and provide password
=> plasma-discover crashes BUT the updates get applied

- Custom settings of the application:
system is behind a proxy and cannot reach Internet without using the proxy

The crash can be reproduced every time.

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Do you always have this problem? Or just sometimes?

Comment 2 Maik 2016-11-08 16:56:40 UTC

On this one machine behind the proxy I have the problem always.
It somehow looks like some request break via proxy.
Nevertheless the packages get upgraded.

The Muon Package Manager works without any problems.
