Description Scott Harvey 2018-02-13 00:14:00 UTC

Application: plasma-discover (5.12.0)

Qt Version: 5.9.1
Frameworks Version: 5.42.0
Operating System: Linux 4.15.3-041503-generic x86_64
Distribution: Ubuntu 17.10

-- Information about the crash:
- What I was doing when the application crashed:

Attempting to download a diff utility.

- Unusual behavior I noticed:

The app had been open, but frozen on "checking for updates". Even though it desaturated and closed when I clicked the window button, no crash report was kicked off at that time.

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

Comment 1 Aleix Pol 2018-02-22 18:19:50 UTC

Can you reproduce? Providing a backtrace with debug symbols would be very welcome as well.

Comment 2 Scott Harvey 2018-02-22 20:07:00 UTC

I can't reproduce it right now. I installed a few random things with no problems at all. I know there's been a few system updates since I originally reported this, so perhaps whatever random combination of factors that caused the crash has been eliminated. I believe you can close this as un-reproduceable. If Discover goes down again, I'll try to get a full backtrace for you.
