Created attachment 105175 [details] Kubuntu 17.04 dump I can confirm this bug on Kubuntu 17.04, see the attached dump from the KDE crash reporting tool.
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.
Happens here too with the same stacktrace as in #4
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: Application: Discover (plasma-discover), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
