Description wottanksplayer 2018-06-14 18:33:21 UTC 
Application: plasma-discover (5.13.0)

Qt Version: 5.11.0
Frameworks Version: 5.47.0
Operating System: Linux 4.13.0-45-generic x86_64
Distribution: KDE neon User Edition 5.13

-- Information about the crash:
- What I was doing when the application crashed:  Using FireFox to browse KDE's website for KDE developed apps to install onto KDE neon.  Some applications were being installed while doing this.  I wish I could report which were being installed but I don't have a screenshpt for that.

- Unusual behavior I noticed:  none

- Custom settings of the application:  none

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

This backtrace is useless.
It may very well be a bug upstream.

If you can reproduce, can you do so from the terminal in case there's any outstanding information?

Also steps to how to reproduce would be welcome as well.

When I found this package (Discover tried to find more packages), I opened information about FSLint and clicked on Install button, but nothing happened. Then I clicked again, and search results disappeared completely. After this I tried to clear search query, and Discover closed with error.

We should find a way to reproduce this, it looks like a rather common one, despite the crash being deep in Qt.

Figuring out which is the faulty Repeater would be useful as well.
Comment 29 Nate Graham 2019-06-10 19:25:09 UTC 
No reported crashes after 5.14.5. Let's call this one fixed unless we get any new reports with the same backtrace.
