--- Comment #13 from Manuel Stahl  ---
Still crashes in Ubuntu 16.04.3 LTS. Since the stacktrace is different, should
I open a new bug?

Application: plasma-discover (5.8.8)

Qt Version: 5.6.1
Frameworks Version: 5.36.0
Operating System: Linux 4.13.0-32-generic x86_64
Distribution: Ubuntu 16.04.3 LTS

-- Information about the crash:
Discover showed upgradable packages in sys tray. After clicking on "Update
all", the updates were performend and Discover crashed.

The crash can be reproduced every time.

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

nullptr implosion.

I have seen this triggered thusly:

- open discover
- start update
- click on a deb or somesuch in dolphin
- discover gets focused with package install view
- click install
- wait a bit
- click on update section in the left hand side pane
- crash

better trace:

I confirm this bug on a fresh installation of Kubuntu 17.04.

I can't attach a log because drkonqi crashed too while I was reporting the bug.
